Exercise and getting/staying in good shape is so unbelievably fun at Block. All the coaches are so knowledgeable and motivating. I was fortunate enough to continue exercising fairly rigorously through my pregnancy. Near the very end, when I was pretty large and getting ready to pop, all the coaches gave me modifications that I could do and still get the most out of the workout. The amount of support they provide is incredible. Block is truly the best gym Ive ever been to.

BLOCK is an amazing space to transform your body and connect with other individuals who are also seeking to live a healthier lifestyle. The Coaches are knowledgeable, great at explaining what is needed, and invested in each persons journey. I used to hate working out and avoided all the meat market gyms. Now I love working out and pushing myself to see what Im capable of without any pressure from others. I highly recommend BLOCK Fitness!

I have been part of The Block Collective since it opened. I was excited to find a personal trainer who could design a strength and conditioning program that worked for me and my needs. Joseph Hawthorne and his team provide an atmosphere that combines fun with fitness and wellness. For the imperfect, this is the perfect place!

Block Fitness has been a game changer for me since I started in April, 2021. The trainers are super supportive and are there to correct your form if you need it. Block changes their workouts frequent enough (monthly) to keep it fresh and the classes are small enough to get the attention you need. You're treated like a member of the Block family from day one, not like a number when you scan in elsewhere.

I think the word "Collective" in the name really explains the experience at Block Fitness. You really feel like part of the community. Top notch coaching with a fantastic vibe. I never thought I would feel so at home at a gym. I actually look forward to my workout days.

What is cool about this gym is that all the coaches have their own unique way of teaching so you can find one that fits your personality and inspires you to be your best. But the best thing about Block are the members who truly become your friends. Everyone knows each other and is supportive and fun!
