Open up your chest and work those abs with a lying fly.
- Lie on your back with your hips and knees both at 90-degree angles. Using your low abs, press your lower back into the mat. Raise your arms toward the ceiling, palms facing each other, keeping the elbow joint slightly bent.
- Keeping your torso stable, open your arms out to the side until your elbows are about two inches from the floor.
- Raise your arms back to the ceiling, bringing the weights together over your chest. This completes one rep.
- Do five reps to complete a set.
Rest for at least 90 seconds, then repeat this entire circuit four more times.
