Target Muscles: Chest
Equipment: Dumbbells
Start: Lie on a flat bench holding two dumbbells up over your middle chest with an overhand grip and straight arms.
Finish: Pinching your shoulder blades back, bend your elbows and slowly lower the dumbbells until they're right next to your armpits, a few inches higher than chest level. Pause, then press the dumbbells back up, bringing your hands close together without clanking the weights.
