If you're recovering from an injury or even just some minor soreness/achiness, how can you tell when it's safe to start transitioning from resting and taking it easy to pushing yourself and getting back to more normal or strenuous activities - taking it to the next level to challenge yourself more?
Related question: When working out, how do you know if any soreness that you feel during or after the workout is a good, positive, normal ache indicating that "my muscles are getting stronger and I got a good workout" versus a bad, negative ache indicating that "I did something wrong and I pushed myself too much or hurt myself"?
