I do 3 different types of squats, with heavy weight (for me anyway) 85lbs. I do usually 4-5 sets. I do stationary lunges holding 15lb dumbells, 4-5 sets. I also have a booty and it's getting smaller and firmer. I'll have to post another picture of it soon. In other words, don't be afraid! I lift heavy always, sometimes I will alternate between med/heavy/light if I need to switch things up. These are all things I learned here , a lot of it I owe to Built! you go girl!
