What would you say to a middle aged guy who hated PE in school and now wonders about joining a gym.

Later in the fall. Now, I am biking (mostly) up to 20 miles a day when schedule and weather allows

But in Michigan, that will come to a screeching halt roughly around Thanksgiving, give or take a few weeks due to weather (specifically snow and ice making it unsafe).

And, wondering if, and thinking should, I should do more than just biking, which is a cardio workout. Think I should learn to do strength training as well.

Gyms -- what can you tell me. I know they vary, but thinking something like an LA Fitness -- is that really about health, not a pickup joint? I would be embarrassed at first, but think I could cope. And I think maybe some initial professional help would be good from a trainer or exercise physiologist?
