Lie on your side on a flat surface with your body in a straight line. Place a barbell across your hip, using a pad or towel for comfort. Keeping your core engaged and legs extended, lift your hip off the ground by contracting your glutes. Pause briefly at the top, then slowly lower your hip back down with control. Perform all reps on one side before switching to the other.
Log your barbell lying lifting (on hip) sets in 1RM.fit and watch your estimated 1RM update automatically as you get stronger.
