Don’t Just Take Our Word For It

I have tried so many diets and exercise routines that I can’t even count them all. I simply could not lose any weight no matter what I did — that is until I started using Stonecrysus. After just a few weeks my weight has already dropped and I couldn’t be happier with my progress!

Before I started using Stonecrysus I thought I ate pretty well and did enough exercise to be considered healthy. However, I was gaining weight and generally didn’t feel great about myself. Stonecrysus has really opened my eyes as to how unhealthy my choices were! With Stonecrysus I am starting to understand what it really means to be healthy.

While I have never really struggled with my weight, I have always wanted to make healthier choices. But I didn’t want to put in the effort to figure out what foods were healthy or how much I should be exercising. Stonecrysus has really helped my figure this whole “health living” thing out and now I look and feel better than ever.

I have been lifting weights for about a year and after about 10 months my strength started to plateau. I tried altering my diet but just couldn’t figure out the right macronutrient ratio. After just two weeks of learning my body, Stonecrysus’s recommendations have had a real impact — slowly but surely my lifts are getting heavier.
