I go to the gym every single day. My gym is open 24/7/365 which is the main reason I joined it. I wake up every single day at 2:30AM, and I am in the gym by 3. I do 3 days of weights followed by a day of cardio.
Day 1 is chest, shoulder, and triceps, all of the pushing muscles.
Day 2 is legs and abs.
Day 3 is back, traps, and biceps, all of the pulling muscles.
Day 4 is cardio, either 1 hour on the treadmill or 1 hour on the bike, then abs.
Today for instance, I was feeling really good, so I did 1 hour on the treadmill, 4 mph, at the max incline, followed by 40 minutes on the bike with the resistance at 8, then abs.
Just get off you ass and do something. Anything is better than just thinking about and putting it off.
