I am from Bulgaria,my english is bad,but you understand me… the squad is very good exercise for all body,but this exercise is not so good for very hight people(188sm+…) deadlift to.because this exercises are very hard,they build big strenght,but are very dengerous when you do 2-4 reps,i have a problem with my back when i use deadlift,i do deadlift with 215kg x 4 reps because the position of my body is not like the position like somewone who is 172-179sm.its little difficult for me(i am 186) and just stop do deadlift,but i like do squad!!!
