Fitness

I'm a bit new(ish) to working out and utilized a personal trainer to get me started over the last few weeks. I can't afford to continue using a trainer and was wondering if there was an app out there that helps you build a routine? I looked at Apple Fitness and I don't want videos, just something that can help build a routine such as - 3 sets 12 crunches, 3 sets of 8 standing overhead dumbbell presses, etc. Ideally it would just list out the exercise, number of reps/sets, etc. as a checklist that you can mark as complete as you go. Most apps I have come across are only videos. Any suggestions?
