Strengthen Your Lower Body With This Trainer's 20-Minute Workout

You can perform this exercise seated on a chair or on a bench.

• Sit on the floor with your elbows resting on a bench (or chair, etc.) behind you and a booty band above your knees. Make sure you're seated tall, lengthening through your spine. Do not slouch.
• Open your knees out to the side, pushing against the booty band for resistance as you do.
• Go as far as your hips allow without causing pain, then bring your knees back together. This counts as one rep.
• Complete for 60 seconds.
