Invested Strength Studio has been a complete game changer for me! I have always been a bit nervous about committing to a workout routine, but there's something truly special about ISS and their amazing team. I now look forward to every single appointment, and it's become a highlight of each and every week. I feel better, healthier, and overall happier. Thank you so much for everything you do! #napervillestrengthtraining #lifechanging #grateful

The best training experience - and in particular for weights - I have had. Not only have I become stronger over time but I gained muscle weight throughout pregnancy (instead of losing muscle). Megan and Lucas are the best and really know what they’re doing - they want to help us get stronger!

The protocol to follow if you value your health. Leave cross-fit to the kids (who heal quickly).

Invested Strength Studio is awesome! The gym is clean and they focus on results without unnecessary distractions. Megan is a standout trainer. She is knowledgeable, supportive, and motivating. She takes the time to understand each client’s needs and builds workouts that challenge. Megan’s attention to form and progress ensures you’re not just working hard, but working smart. Training with her feels personalized and effective every step of the way. If you want a gym where you’ll truly see progress, Invested Strength Studio is a great choice! :)

Lance Rubin and my wife Michele Rubin are excited to be back at invested strength on their relaunch as Megan has a very well controlled studio climate controlled 1 oh one personal training, medics and Nautilis machines that are high caliber. Also she has air purifiers and they wipe down the machines after each client What I like about the places in 20 to 30 minutes you’re able to achieve flexibility, strength and aerobic cardiovascular fitness in the trainers of their one on one with you the whole way to make sure your form is right on. I walk out of there feeling invigorated and ready to go at 71 years of age. I’m in the best shape of my life. My wife Michele had two knee replacements last year and she’s back training again and she can use all the machines and she’s excited to build a high level of strength. You know we’ve got grandkids to go chase after I highly recommend anybody near investor strength in Naperville and surrounding area give a call check it out. You will not be disappointed. I’m happy to be back there as part of the family

Megan and her team are fantastic! I didn’t have any gym experience and I was intimidated about the machines, but they walk you through everything and meet you where you are. I’ve gotten stronger, more confident, and I highly recommend them!

I was present for opening day; I believe in Megan and the method of investing in my raw potential to seek positive results. I recommend everyone try and live a healthier and happier life.
