As someone who has exercised daily for several decades I can become tediously evangelical when espousing the benefits. When a friend who's spending a month at a health retreat to lose weight asked me at the weekend for my tips on an exercise regime she could stick with, I made a valiant effort to quell the evangelist. Instead I gave her a summary of observations:
walking is free and hard to beat;
exercise bikes should be taken straight to a dusty corner of the shed to save you the trouble of doing it soon afterwards;
paying fees does not make the exercise in a gym any better than what can be had free on the footpath;
morning is the best time to exercise, because getting out of bed becomes easier than setting out weary at the end of a long day;
pausing an exercise program for winter is likely to be a permanent halt;
the commitment to exercise is greater when you're part of a group or with a companion;
boot camps led by fitness trainers are a great way to start;
it's the sticking with an exercise program, not the exercise, that is hard.
What's stopping you exercising? Or what keeps you exercising? What would you say to my friend?
