When it comes to solo workouts, many women tend to focus on working their legs and core but forget all about their upper body. However, if you’re going for that allover toned look (and well, aren’t we all?), it’s time to stop ignoring your arms! Expert trainer and KIND spokesperson Jennifer Cohen created a fun and effective arm workout using moves from her new book Strong Is the New Skinny to help you build strength and sculpt the defined arms you’re pining after. Repeat this seven-move circuit three times for a complete arm workout.
