Hello,
I was curious as to what energy systems should be emphasized in training when returning from a 3 week break due to an injury. I know i need to ease back into it, but once I am fully recovered, what should i be focusing to get back to where i was before the injury. For context, I started my base phase in july, and have slowly been building in more interval work over the past six weeks prior to my injury that started three weeks ago. I guess the real question is, what energy system loses fitness the quickest after a 3 week break.
Thanks in advance
