Incredible arms are your sexiest accessory and the surprising secret to epic abs. Few things are more empowering than having strong arms. (Busting out real push-ups; lifting your carry-on into the overhead compartment in one fell swoop.) That type of confidence never goes out of season.

We’ll even throw in a set of shoulders. (They’re considered among the easiest muscles to define since they’re less likely to store fat than the lower body.) This workout is designed to tax the large muscle groups first to build serious strength, then shape with higher-volume reps using lighter weights.

These moves are firing up your core and improving your posture. Perform this routine two or three times a week: Do the following moves in order, completing as many rounds as you can in 15 minutes, resting briefly only when your form starts to falter.

You’ll want a lighter pair of weights (three to five pounds) for the alternating front-side raise and dumbbell biceps curl, and a heavier pair (eight to 15 pounds) for the bent-over dumbbell row.

1. Pike Handstand Hold:
