I've been using ExRx since the early 2000s to supplement my workouts. It has something for you whether you've been working out for years or are just getting started. For me, the exercise directory has been so useful in my training (Weight Training section in app). I highly recommend you fiddle with it. It's early in it's development so it's not as "sleek" as most apps but it's so useful. You'll be glad you tried it and I'm sure it'll only get better from here.

The only negative on this app is how it caps search results. If you search only by muscle, 9 times out of 10 it will give an error saying there are too many exercises that match and to narrow the search. Not really that helpful when you're looking for new exercises.

100 exercise results are not useful. If you want to view exercises by muscle group only, you should use the browse feature. The search/filter is to find specific exercises by multiple criteria including Name, Utility, Lateral Pattern, Movement Pattern (plyos), Muscle Group, Mechanics, Force, Apparatus, or difficulty level (bodyweight exercises).
