These look brutal! The somersault squat has apparently been around for quite a while (I found videos from 2013) but they’ve only recently gone viral. I’ve now seen them done with a kettlebell, a dumbbell, a smith machine, a leg curl machine, and with plates stacked on the thighs. Give them a try if you want bigger quads. | Bret Contreras

I approve! This is a great exercise. Perfect for a reverse hack squat movement - good morning on the way down, glute dominant squat on the way up. Each phase works the glutes but the alternating ham/quad stimulus may allow for more reps hammering the glutes. | Bret Contreras
