Begin with two 5 lb. weights, one in each hand. Stand on one leg in a warrior 3 pose, slightly bending the knee with the other leg extended straight behind you and your upper body leaning forward so you look like a letter T. Try to keep your hips level so your back toe is parallel, pointing down to the floor.
Pull both elbows back by your sides in a 90-degree angle. From there, straighten your elbows contracting your triceps into a kickback, then return back to a 90-degree angle. Make sure you keep your chest open, shoulders rolling down and back. This works the triceps, and the standing leg and your core has to work hard to help keep you stabilized.
Repeat 16 to 24 times on each side for one circuit. Complete the circuit twice.
Modification: Place the back foot on the floor and do this from a staggered stance, keeping the hinge in the torso.
