If you need some energy

Maybe try a personal trainer. It sure seems to work for me.

I started going after my knee operation last September and have managed to keep it up continuously since then. Without the personal trainer I lack the will power to force myself to do things like sit-ups or pretty much anything which is not fun. However after a session I tend to feel great all day.

I go to a pretty tiny gym where I am often the only client, and every session is different which makes it more fun.

Here's the view from the gym. (It'sa pretty large image so click the link then click view all sizes, then the largest image if you want to see it big.
