Well, it seems all such as you eventually find too many conflicts to continue regular exercise.
But it is a good conversation piece for a few weeks with your buddies.
Millions of Spas, gyms, weight loss people, etc., depend upon you people!

It's hard to beat the ellipticals in terms of bang for the buck. I go to the World gym about 5 days a week. I go straight to the elliptical machines, do about 45 minutes, then leave. I can burn 800 calories in that time. The nice thing about the ellipticals is that you work your arms and legs at the same time, so you max out your cardiovascular system and build up your major muscle groups, all at the same time.

I'm sure some "gym rat" will say that you have to do circuit training, and I won't disagree, but I see a lot of people buy into the complicated routines and nutritional supplements, and they are in no better shape than I am. The supplements in particular are designed to pad the gym's profits more than anything else, and they make no difference whatsoever to your health.

The main drawback to the ellipticals, or any aerobic machines, is that they are boring. The World gym has a row of TVs on different channels, and you can take some headphones to listen to the audio, or you can take an MP-3 player to listen to your own music. Whatever you do, please don't spend the time yakking on your cellphone. That is SO annoying to the people next to you!!

I used to distance run, but my knees started getting sore, right about when I turned 40, so I switched to the aerobic machines. If your joints start getting sore, switch to low-impact training before you tear up your joints permanently. I had a couple of friends who kept running too long, and they ended up needing surgery just to be able to walk normally. Also, if you are just starting an exercise program, I can't overemphasize it enough--start out slow and easy, then build up your workout very, very gradually. It's far more important to stay in the program than to make rapid progress early on. Most people get disappointed when they don't progress rapidly, and then they give up.
