I've actually finally found a workout method that works for me:
FitOn! It's free and has thousands of thorough and fun workouts and has given me actual MOTIVATION. I sound like an MLM shill saying all this, I'm just happy I've got something that
works. 
Honestly, seeing Miku as a fitness junkie, funny as it is, makes me happy, because with this app plus my martial arts classes, fitness is finally something that feels accessible and fun to me. I'd honestly splurge on the Miku Protein if it weren't whey...
