my rides and workouts usually leave me fatigued, feeling like my muscles and lungs have been worked, but after a short break I feel energized and can do more. The occasions when I have prolonged soreness or DOMS (delayed onset muscle soreness) it is either because my trainer has suddenly popped the level up, or because something is amiss with my nutrition or hydration. I tend to lose potassium unless I eat my daily banana.

Still the biggest criterion should be feeling able to do another workout and to alternate rest work , baby steps are good.
