Or worse than never going, you'll keep going, but you'll always just do whatever you feel like and never push yourself. Then years down the track you've made no progress, but poured countless hours into the habit.

It's probably not going to work if your strategy is to only do easy things, or only do really hard things. I suspect that the answer lies somewhere in the middle, as it often does, and as ever there is no way to summarise that as a simple and absolute rule, you just have to use your own judgement and self-knowledge to guide you.

People who seek these kind of easy answers are already in a quagmire. The most debilitating belief is the one that there's a perfect, general answer out there that you just have to find.

Unless you are unsatisfied right now, "progress" isn't really important. The most important part of exercising at least semi-regularly is to maintain your condition, and that get more important as you get older. Nobody has the TIME to do everything they might want, you have to prioritize. As Peter McWilliams put it:

"You can have anything you want: No dream is too big to achieve. But you can't have everything you want: We live in a finite world for a finite period of time, but with infinite imagination."
