Muscle all over your ENTIRE body need to be strong and powerful. So a 5k/spin class and a couple planks WILL NOT cut it!

👍 grow muscles, which, having a higher metabolic demand at rest, will help you burn far easier
👍 get you strong and confident
👍 improve metabolism, increase bone density and projected lifespan
👍 improve body proportions
