I try to get to the gym at least three to four times a week.
If you can get to the gym 4-5 days a week, that would be perfect. You can still do chest/tri's, back/bi's, legs, shoulders, and make the fifth day a cleanup day, meaning focus on body parts you may be weaker in.
I spend about two hours every time when I'm in the gym.
I just go to the gym once every few weeks and go training once or twice a week. But it's all pretty random.
In terms of working out, I'm in the gym, maximum, twice a week, but for a pretty intense period of time: two or two and a half hours nonstop. Most of the exercises are body weight. We're talking pull-ups, chin-ups, decline rows, elevated push-ups.
I go to the gym at least 6 times per week.
I try to go to the gym three to four times a week and mix it up with yoga or a personal trainer.
I'm not so much in the gym. I don't push weights.
