If you've been lifting weights for that long you wont be in that bad shape. Or alot fitter than the average joe anyway. Try and play 5 a side aswell, if it's in a actual league even better. That will get your cardio fitness up quick. Hasn't your gym got treadmills, bikes, rowing machines etc?
The gym I go to lift weights is only a 5 minute jog, so I'd be better off doing some cardio once I'm in there, or going for separate cardio altogether. I've definitely got to get back into burpees and skipping, as well as general fitness. Edit: Giving up alcohol isn't really an option, I'm not going to take it really serious and start fighting amateur or anything.
Yeah I'll start doing some cardio at the gym. As for 5-a-side, we've been talking about starting up for a while and I know it'd be a good laugh. Probably won't do it though.
then work on ur cardio and lift weights still lol. or just lift lesser weights w/ more reps to build endurance
