The frog press is a basic core- and glutes-strengthening exercise that also improves stability throughout the lower back, hips, and spine.
Instructions
Lie on your back with your knees bent to 90 degrees, turning them outwards like a frog. Make sure to keep your heels pressed together while flexing your feet towards you.
Tighten your stomach and crunch up, lifting your head and shoulders off the floor, holding this position. Place your arms down by your side, hovering just above the floor.
Straighten your legs away from your body at a 45-degree angle. Return to the starting position, completing the desired amount of repetitions.
Trainer’s Tips
Avoid doing the exercise too quickly. Instead, press your legs in and out slowly and in a controlled fashion.
