Enjoyable, helpful, quirky, every day – Arm workout - trainer for arms Review

I really enjoy this app, with its helpful animations, dozens of interesting and challenging workouts (plus custom options) and happy obsession with comic-book characters (yes, there is a workout called Deadpool). Note that it is challenging, especially if you are older or just starting out--is geared to strength training. Great work.
