I recently completed a 30 day squat challenge. I'm not going to lie, it was HARD. I am blessed with the Italian side of my heritage's genes; wide hips, sturdy thighs and a butt.
My butt definitely changed shape. My waist is smaller and my thighs are AMAZING. I now do squats every time I exercise. No exceptions. Start off slow, do maybe 20 a workout then move up. On my 30th day, I did 250. Now, I do 100 three times a week. There is a difference and not so much "shake" with my fries
