Yes, this exercise is just like it sounds. It’s not only super-specific to running, but it also acts as a core exercise.
BENEFITS:
Arm and shoulder fatigue late in a race or a long run is a real thing—swinging your arms for an hour, two hours, or four-plus hours can be extremely tiring, and this move can help prevent that fatigue from setting in too early. When powering uphill or shifting gears to hit a tempo, maintaining strong momentum with your arms is hugely valuable.
HOW TO:
1
.
Stand in an athletic stance with your feet shoulder-width apart, knees slightly bent, holding a light (1- to 3-pound) dumbbell in each hand, bending your arms 90 degrees at your sides.
2
.
Engage your abs and swing your arms back and forth, keeping your hips facing forward and abs engaged, as if you’re running.
When you do this, you can really feel your core working to maintain your position right over your feet.
