I'm in the same boat. I used to work out 2-3 times a week, then down to once a week. Now I'm back trying to go 2-3 times a week but find I'm not doing as strenuous a workout or covering all major muscle groups. I work out at the gym at the office during breaks in the day so I can't get too sweaty. It's been a few months since I ran regularly too, but that's probably because it's 95-100 F outside.
