They say that running is one of the best exercises to lose weight. I know I always get a great workout when I jog or play sports. The only thing is I find that it is really hard on my joints. When I was younger it was no big deal, but as I get older I am finding that my knees and ankles can't take the impact from running like they used to. I feel pain in these regions after I participate in sports and jogging.
Because of this I have switched from jogging to swimming and elliptic training. Both of these exercises are easy on my joints and they both give me a great workout. I read recently that swimming is actually a better cardio workout the jogging.

I know that not everyone can get to a pool, but elliptical training works great too.
