The Dumbbell Chest Press is a strength training exercise that works the chest, front deltoids and triceps. The model in the video is working on an adjustable bench.
INSTRUCTIONS: The exercise is performed either on the floor, or an adjustable bench, in a supine position. Bend your knees at right angles, and place both feet on the floor, or on the bench, hip width. Exhale and press weights up until elbows are straight. Wrists are stacked over the elbows. Inhale and lower weights until elbows are in line with shoulders. Move slowly throughout the exercise.
Back Position: To protect your back, maintain a neutral spine. The neutral spine position is the halfway distance between flattening and overarching your low back.
