Dumbbell Chest Press (for chest and triceps)
Lie on your back, holding your dumbbells, and bring the soles of your feet to the floor, knees pointing up. Bend your elbows so your weights stack over your wrists, then bring your elbows to a 45-degree angle—your arms should look like an arrow.
Press your entire back into the mat and exhale as you push the weights up over your chest. (Try not to let them bang together!) Inhale as you release back down to the floor, then reset and repeat. Pro tip: If you’re pressing heavier weights, pick up your dumbbells before lying back, as it’s easier on your shoulder joints. Repeat for 10-15 reps or 45 seconds.
