The good news is that if you have plenty of stored glyco­gen, you will re­gen­er­ate ATP pretty quickly and will be able to per­form again ex­plo­sively and pow­er­fully with a lit­tle break in be­tween. This is why you can do re­peated sprints or sev­eral sets of box jumps for more than one round.

Aer­o­bic train­ing, such as dis­tance cy­cling, run­ning and hik­ing, uses oxy­gen and glyco­gen to power your ac­tiv­ity.
