There's not much quick and effective to that kind of absence, the only thing quick is frustration.
Getting back after a break and especially while out of shape is frustrating, and disheartening physically and mentally.
You've basically gotta stick it out for X # of hours until you return to some sort of form. Sports dont build character, they reveal it, so it'll be a test of your work ethic.
If you want some exercises that will push you physically, run 3-4 times a week for over 5 kilometres, do weights 2-3 times a week, and eat healthy / more activity.
Organize matches every 2nd day and try to hit maybe 30mins/1 hr on off days, dont wanna throw your body out.
When you hit the later km's in your jogging, when your chest gets tighter and your legs are rubber that'll test how bad you want it.
