So, basically, I should join a gym? Actually, I have been thinking about varying what I do, and notice what hurts most are the muscles that are used when doing deep lunges up big steps, or maybe what gets worked during squats. I guess part of the trouble with the gym, since I do some upper body just not much, is that I am largely bad at it and don't really care. I looong ago realized that I was not going to attract women by doing it, and I never seemed to get any real size, so I just stopped caring. I sometimes pick it up, sometimes drop it. Either way, it is always more than my life requires, so it is hard to justify the time, and it is boring. Plus, gyms smell and are full of people I generally don't enjoy being near.
Hiking, on the other hand, is fun and I like getting out most of the time. The trouble there, is that while I was almost always able to maintain a level of fitness to do something like a moderate MT Elden trail, day after or day ( I think, since I never did it), I find the fitness level needed to do a 4000 to 5000' hike is different, especially when steep. Kimball is currently far harder than I remember Humphrey or Elden to have ever been. Sadly, with the higher temps so early and my allergies which have been noticeably worse near the front range canyon riparian vegetation, my spring big hikes may be nearing an end.
Nothing more enjoyable than a good hike out of town.
