Growth And Goals With Innermost Insider Amy Costello

Hi Amy! Can you tell us a bit about how you got into your fitness journey?

Hey my Innermost faves! I was always involved in sports at school and loved running, but it was on my travels to Sydney, Australia, that my passion for fitness as a real, positive, daily part of my life, kicked off.
I love the lifestyle in Sydney. Everyone is really invested in their health and fitness and that fuelled me to get my Personal Training qualification and start going to the gym (I’d never stepped foot in a gym before this!), where I learnt absolutely everything I could about functional and resistance training. I read books, I watched technique videos, and I put all of it into practice in my own training and programming. But this was just the beginning!

How did your passion for fitness begin to translate into your full-time job?

Whilst living in Australia, I met Mike, who is now my fiancé (woo) and my business partner in the fitness empire we are building! 
It actually started when my Aussie visa was due to expire, and we were game-planning ways that we could stay together and avoid doing the long-distance relationship thing. At the time I was coaching at an F45 studio in Sydney, and after a bit of research, we realised there was only one F45 studio in London - so Mike got thinking - why don’t we see if we can open one! 
It then all happened very fast - within a couple of months we had signed with F45 to open our own studio, had packed our bags and were moving to London. 4.5 years later and we've built an incredible member base and community at F45 Tottenham Court Road, and also launched our own fitness retreat company, Salt Escapes, where we run fitness holidays at various beautiful destinations around the world! 

What was more challenging, opening your F45 Studio or launching Salt Escapes? 

I would have to say F45. It was our first business so there was a lot to learn and a lot to prove. We made a heap of mistakes and knew next to nothing about business, but we worked our little asses off to build our gym into what it is today. 
When we launched Salt Escapes, we already had an engaged, interested customer base in our clients at the gym, so it wasn’t SO terrifying to launch! Also, with it being our own brand and company, there were no limitations like with F45. Instead we were free to branch out, be adventurous and see what works. This is how we like to do things!

How has your business evolved through lockdown? 

Wow, it’s been a testing year. We lost a lot of members throughout the past year. Being located in central London was a huge advantage for the first few years of business, but when lockdown hit, everyone just disappeared! 
It’s almost as though we’ve had the chance to start from scratch, which has meant we’ve had the opportunity to re-evaluate everything from our finances, processes and sales strategies, to our membership offering and client-relationships. 
From that perspective (and ONLY that perspective), it’s been great for us. We’ve been given the opportunity to build our business back stronger. Nine months of closure allows you to do a lot of reflecting. 

How have you personally evolved throughout the last year? 

Well I’ve managed to avoid packing it all in and moving to a tiny island in the middle of nowhere - does that count?! 
Haha, no but seriously - I guess for me, it’s been the year I’ve actually understood what it means to look after your mental health. It’s been a really challenging year to own a gym and a travel business, and my sleep and mental health has taken a battering. 
Realising the importance of “self-care” (sounds cheesy, but it’s a whole vibe) has been a game-changer. For me, it’s walks in the park, my daily 10 minute Calm, switching my phone to Do Not Disturb, and prioritising learning (books, podcasts, journals). 

What does the word ‘growth’ mean to you?

Aside from #gains? Ha. 
In the past couple of years - Mike and I have started saying to each other, and our team, “we like solutions, not problems”. Look, in work, training, life, there are always going to be problems, difficult people, and tough days. I used to obsess over the problems to the point they’d keep me awake at night. Now the minute a problem arises, I start thinking about the solution. Because there’s always a solution if you look hard enough, so what’s the point in stressing over things you have the power to do something about? 
For me - that’s growth. Pushing forward, maintaining a solution-driven outlook whatever is thrown at you, and working out how to move past problems - adapt, reflect, learn. 

How do you push past plateaus?

I think the most important thing is that you recognise you’ve hit a plateau. Whatever it is you’re trying to change, be it weight loss, muscle gain, fitness levels, or whether it applies to work and productivity. I love to track everything. I write down all of my workouts, including the reps I’ve done, the weights I’m lifting, and even notes about how I felt during and after the session. This helps me clearly see when I’ve plateaued in my training, and encourages me to then reassess my goals and make a plan to push forward. 
There are so many ways to mix things up. If it’s a training plateau, maybe try hitting the gym with a friend, trying out a different class, or getting a PT for a few sessions to give you some fresh ideas and perspective. 

What aspect of your life do you struggle to develop most? 

For me, it’s definitely finding balance. Running two businesses doesn’t usually allow for much down time, especially as I work with my fiancé, which means that we’re always either at work or talking about work. I really love working for myself, but it’s definitely had a big effect on my social life. Any 'time off' I do get, I usually feel like I just want to chill out alone. I definitely find it a struggle to maintain or build more meaningful friendships these days. Don’t get me wrong - I have a whole heap of wonderful people in my life - I’m just not that hot on messaging back or letting my hair down and going for a night out these days. 

Do you set yourself goals? How do you make sure you achieve them?

All the time! But I read a great book recently, Atomic Habits by James Clear, which taught me about the importance of goals that are specific and actionable. He says goals are good for setting direction, but systems are best for making progress. I can resonate with this from my own experiences, and from watching so many clients set themselves goals, and then feel like they’ve ‘failed' because they’ve been so focused on the end goal, as opposed to making small, actionable, daily changes to get them there. 
So for example, a small goal of mine at the moment is to drink more water as I’m generally pretty bad at this. I’m making this a habit by setting out my bottle of water before I go to bed each night, so I see it first thing in the morning. I tell myself I can’t leave the house for work until I’ve had 600ml water. I also use a water tracker app, which sends me little push notifications throughout the day. System in place, and so far it’s working and I feel great! 

What is your greatest life accomplishment?

It’s got to be building Salt Escapes. Mike and I have been on the same page since we met. We wanted to create a life where we could work for ourselves and travel the world. We’ve achieved that with Salt Escapes, and there’s a lot more to come! 
On top of that, I don’t think there’s any greater feeling than being in a beautiful part of the world, with a bunch of amazing people who have just had the week of their lives, and have been inspired beyond measure, and realising that you made that happen. 

What’s one goal you’re going for now?

Work goal: Building my businesses back up in a post-pandemic world. We’ve got 9 Salt Escapes trips on the schedule for this year and I’m going to do everything in my power to make them all happen. I just need Boris to play ball! 
Personal goal: Mike and I want to buy our first house by the beach. It’s definitely a longer term goal, but everything in our foreseeable future is now driven by this end goal. We’re focused on a future of beach walks, BBQs and puppies! 

What are the benefits of having a growth mindset?

The opportunities! Personally, I didn’t do too well at school. I didn’t get the point of learning for the sake of learning. But I’m pretty proud of the fact that through hard work, applied knowledge and a lot of determination as an adult. I now own two businesses, work for myself and get to travel the world. 
Natural talent or academic intelligence is one thing, but a growth mindset allows you to experience success, build resilience and overcome challenges, all through a simple shift in your perspective.

What Happened To My Training Over Summer (Honestly)
I did not train well this summer. A holiday to spend time with my family, a run of work trips, a couple of injuries I was trying to cope with (left shoulder and right forearm for those who are interested). If you'd asked me in June how consistent I'd be over the summer, I'd have said very. I was wrong. Most people quietly assume the founder of a wellness brand has this figured out. The truth is I run a brand, I try to have a life outside it, and summer is the season where routine goes to die for almost everyone I know. I don't think that's a personal failing. I think it's just what a normal year looks like. What I want to talk about is what actually happens to your body when this happens, because the research here is more reassuring than you might expect. What detraining research actually shows There's a real body of science on this. Strength and cardiovascular fitness don't decline at the same rate, and they don't decline anywhere near as fast as people fear. Cardiovascular fitness is the first thing to soften. Your VO2 max starts drifting down within a couple of weeks of stopping structured training, because your heart and blood vessels adapt to demand quickly in both directions. Strength is a different story. Studies that track people through a few weeks off training consistently find that measurable strength loss is small, often barely noticeable, for the first three to four weeks. The muscle itself takes even longer to shrink in any meaningful way. Several studies looking specifically at detraining periods found that visible loss of muscle protein and structure often doesn't show up until somewhere between five and eight months without any training at all. A summer of patchy sessions is nowhere near that. The reassuring partThe part I find genuinely reassuring is what's called muscle memory, and it's not just a phrase people use to feel better about a break. When you train, your muscle cells add nuclei, essentially more control centres for building protein. Research shows those nuclei stick around for months after you stop training, well past the point where the muscle itself has started to shrink. When you come back, you're not starting from zero. You're reactivating machinery that never actually left. That's a large part of why people who return to training after a long break tend to regain lost strength and size far faster than it took to build in the first place, often within four to eight weeks depending on how long the layoff was. Some of you might remember this happening post-Covid. So if you had a summer like mine, the honest scientific answer is that you probably lost less than it feels like, and you'll get it back faster than you think. What I'm actually doing this month Nothing dramatic. I'm not doing a reset week or a punishing comeback programme. I'm just going back to five structured sessions a week, prioritising the compound lifts I know well, and being honest that the first couple of sessions will feel harder than they did in June.  Don’t forget your proteinThe other thing I'm paying more attention to is protein, simply because it's the one lever that makes the rebuilding phase more efficient. Adequate protein intake supports the muscle protein synthesis that's doing the actual work of restoring what softened over summer. I've been leaning on The Health Protein for this. It's plant-based, built around pea and brown rice protein for a full amino acid profile, with glutamine in there to support recovery. If you'd rather stick with a whey based option, that's a completely reasonable choice too, and The Strong Protein remains built for exactly that. If you had a messy summer, you're not behind. You're just at the start of a normal, unremarkable return to routine, and the research says that's a far shorter road back than most people assume. Forward this to anyonre you know who is dreading their first session back. I'd genuinely like to know what generally works for you post-summer. Structured plan, just showing up once, anything. Reply and tell me. Even if it’s a one-liner, I’d love to hear from you. Read more
Time To Get Back to Work(out)
Your inbox is about to fill up with a very specific kind of email. "Back to training." "Reset your routine." If you've been on a supplement brand's newsletter list for more than a year, you've seen this before.  September is the industry's second run at January. Slightly quieter, but just as calculated. Gyms fill back up, summer holidays end, and every brand in this category knows there's a window where people are motivated and slightly guilty about the last two months. So before you see any of it, here's what I think is actually worth paying attention to when you're getting back into training after a break. Progressive overload is still the name of the game Your body adapts to load over time. If you're coming back after a few weeks or a couple of months off, the temptation is to jump back in at your old numbers. Don't. The evidence shows that a short break doesn't erase your progress, but going back in too hard, too fast is how people get injured (speaking from experience). Start below where you left off and let the load build over two weeks. It’ll come back faster than it left. Protein quality matters more than protein hype Every September, protein marketing gets louder and less precise. Here's the mechanism worth remembering: muscle protein synthesis responds to leucine, and you need roughly 2 to 3 grams of it per meal to properly trigger the response. That means spreading protein across the day, three or four servings of 20 to 40 grams each, does more for you than one enormous shake after training and nothing else.  Creatine: maintain, don't reload If you took creatine before your break and stopped, you do not need to reload. That's a hangover from old protocols designed to saturate muscle stores quickly for research purposes, not something you need for a training restart. A standard maintenance dose, 3 to 5 grams a day, gets you back to full saturation within about two to three weeks on its own. No loading phase, no timing games. Just consistency. Where I'd put my money For protein, my recommendation is to try The Health Protein or The Fit Protein. Both are plant-based, built on a full amino acid profile rather than a single source, and formulated for exactly the kind of consistent, unglamorous daily use that actually moves the needle. If you prefer whey, The Strong Protein and The Lean Protein are still exactly what they've always been, and there's nothing wrong with that choice either. The key is picking one and being consistent with it. For the training side specifically, this is where The Power Blend does its job: creatine at a proper maintenance dose as your training volume climbs back up. It's built for exactly the return-to-training window this email is about. One thing worth saving from this email if nothing else: creatine maintenance dose is 3 to 5 grams a day, no reload needed, and it takes about two to three weeks to fully resaturate. That's genuinely useful whether you buy anything from us or not. If you've got a return-to-training routine that's worked for you, or a question about any of this, just hit reply. Read more
