This is my personal favorite style for squats. It’ll help work out your butt, legs, and shoulders. You don’t necessarily need weights, but I recommend you use light free weights if you do. How to do V-Squat’s properly:
A) Stand with feet wider than shoulders in front of a bench and hold a dumbbell in each hand. Raise arms to shoulder height as you squat until butt barely touches the bench.
B) Immediately rise up and lower arms. Do 12 reps. On the last rep, pulse up and down 2 inches from the bench 12 times for extra firming.
