Busy enough, but not too much to go to the gym 4-5x a week. People who say they have no time have either never exercised seriously, or don't want to. It's like any excuse system - there's always a way out if you want one.
The second paragraph is more astute and relevant. Lifting was my life from 19-24. I'd get up in the early morning, go do my cardio at a small local gym, come home, shower/eat, then go to a bigger gym for my real workout. Did that 5-6 days a week. Was on the diet, got lean enough to pass for a swimsuit-style magazine model with decent arms/legs, and was genuinely happy with my look.
Then I got older and less competitive. Being big or lean didn't matter as much. Women started to care less about that and more about other things. I quit clubbing. The diet got boring and I went back to eating like a normal person, which in my case means about 2000kcal more than average (appetite holdover from rugby). I put on weight. The gym became less attractive. I'm injured in several muscle groups. And finally I quit working out altogether 8 months ago. It shows. I'm smaller than I used to be even 3 years ago, and obviously not lean anymore. I'd say I look about how bigmc was in that guitar video. It's a long road back and I usually run out of steam about a few weeks.
I agree with the excuses, however at the moment I'm spending one day a week at home in Christchurch and travelling the rest of the time. I have my Six Sigma green belt certification in Melbourne next week which is another 2 weeks away. I suppose I could find a gym in the hotel area but it really makes it difficult to have any sort of consistency. But I'm maintaining shape through push-ups and sit-ups in the hotel room. It's always been easy to eat relatively clean too.
And age does bring injuries. I had a rib injury 6 weeks ago which made pressing movements hard and when that got better, I sprained my ankle playing badminton. My first day at my new job I was wobbling around everywhere. It's only now I'm healed up again. This shit would never have happened at 23.
