I like how maleable this app is! I have lots of options should something be harmful to my body. I have found it a helpful and pleasant experience. I would like an option where I can also track warm-ups and cool downs outside of the challenges. The step tracker is out of sync with my time zone, so it is not trustworthy. According to it, I have walked 2000+ steps this morning, and I just got up. My bed is not that far from the rest of my home.

There's always the skepticism about an exercise app helping to do what it claims. I've been using muscle booster for 3 weeks now and I feel that it's helping me get results in a steady pace. I like that it provides guidance on exercises, offers alternative exercises that help me gain the same benefit if I have issues with exercise they suggest, and provides a plan for routines taking a lot of the guess work on what I should do, while providing a decent challenging workout.

I cannot listen to music and use this app at the same time with my headphones simply because this app's sound will not work. I've checked my sound settings, app notification settings, uninstalled, reinstalled, and the app continues to be silent. They've reached out before but I'm tired of this app! Avoid it and download HEVY! Muscle Booster, don't reach out anymore bro, I'm out! ✌🏾
