VCQ-0398
How can I tell whether I have an energy problem, a stamina problem, or a recovery problem?
Use timing to separate them. Energy is usable capacity or alertness before activity; stamina is how long you can sustain effort; recovery is how quickly you return to baseline afterward. A person can have one problem without the others. Choose the category that matches when the limitation appears before comparing products.
