You'll need a flat bench and two sets of dumbbells: a lighter set and a heavier set. The lighter set will be used for the shoulder exercise; the heavier set will be for the biceps and triceps exercises.
A1 Seated Biceps Curl
A2 Skull Crusher
A3 One-Arm Side-Lying Rear-Delt Flye
Perform 2-4 sets, 8-16 reps per exercise, resting 1-2 minutes before repeating the sequence.
To remain more stable on the bench during the flye, hook one foot around the top of the bench. Keep your down hand on the floor, which requires you to position yourself with the top of the bench under your armpit.
Within the realm of training for greater strength, muscle mass, and endurance lies an area of science that remains relatively untapped: Neuroscience. It's indeed the uncharted waters in the vast ocean of the science and practice of resistance training. That's because so little is known about how the nervous system actually works.
