Many stores are pushing exercise equipment to lure the sort term demand created by New Years resolutions. Many people don't get regular exercise, but if f you are serious about such things a couple of recommendations.
The most important advice is to decide if you have a chance of using any of it and what sort of program works for you. Perhaps walking or running is best. Some find activity monitors sufficient and others like health clubs and pools. Investing a bit of time and money trying out things and consulting with a personal trainer makes a lot of sense. For me it turned out a good approach is a high quality rowing machine in the basement.
The best time to buy new exercise equipment will be in about two months (at least in Northern climates) as the stores make way for warmer weather sporting gear. But a better way may be to wait until April and May and watch local home sales as well as Craigslist. People are beginning to clear out garages and basements and are looking to get rid of machines that were used a couple of times and abandoned. We've managed to get a fair amount for the price of hauling it away. One of the people we "helped" told us looking at the thing was a regular reminder of his failure to use it, so our taking it was a big favor.
You do have to be beware as there is a lot of junk out there that isn't worth the effort required to haul it home and, of course, you have to want it and be willing to use it. Motivation and realism are important. I have a regular program and staying motivated is a big issue as it is time consuming and boring, The trick for me has been to get it out of the way in the morning and to fill in the time by time shifting periods I would normally use for news and recreational radio listening with an iPod. I'm currently auditing an excellent class on the history of English and I've used the feedback and encouragement of a friend who has acted like a remote personal trainer.
and there is advice on exercise - and life in general - for teenage boys from the YMCA c.1919
girls weren't left out either -- from 1922
