Add this right after your 3-4 sets of squats.
This exercise works the Quadriceps, Hamstrings, and Buttocks.
1. Stand, feet together, a dumbbell in each hand.
2.Take a giant step with your right foot, bending your knees so
your right thigh is parallel to the floor and right knee is directly
above your ankle.
3. Bring your left foot forward to meet your right, then take a
giant step with your left foot.
Take 20 steps forward, then turn around and take 20 steps back to starting position. Beginners should do one set; others should do 3-4.
If you squat around 315 use 50 lb dumbells.
You'll be lucky to complete 2 out of 4 without dropping
to the ground at least once.
Have someone drive you home after this workout... LOL
Then finish with 3-4 sets of stiff leg dead lifts. If you can
Did I say finish ?
Don't forget the hack squats !
