How-to: Tricep Kickback

Stand with feet hip-width apart on the center of the band, holding an end in each hand and bending elbows to 90 degrees. (Hold the band so there's no slack.) Keeping your back straight, head in line with your torso, and upper arms glued to your sides, hinge forward at the waist. Extend both arms back (as shown), flexing your triceps muscles as they straighten. Bend your elbow again to bring your hands forward. Do 20 reps.

No gym or band? Do the same move using dumbbells or full water bottles instead. You won't get the increased resistance you get with the band, but the weight will tone your arms almost as well.
