I hurt my lower back doing a failed deadlift attempt. Nothing terrible, but I feel a mild pain there.
When can I go back to weight lifting?
Similarly, my hand is sore (from a poorly done impact...) when I grip hard - do I have to hold back on weight lifting?
In general, how do you know if you're better sitting it out, or are ready to go back to the gym?
UPDATE: My hand injury was punching a wall too hard. My middle knuckle took the impact. Not enough to break the skin - not even a visible bruise. But my hand became sore, especially when gripping something, for a few days. That's mainly gone.
