Position yourself under a Smith machine bar with your upper back supported on a bench and feet wide with knees splayed outward like a frog stance. Drive through your feet to lift your hips upward, squeezing your glutes at the top, then lower back down with control. Keep your core braced and spine neutral throughout the movement.
Log your smith frog hip thrust sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
