I've recently started

doing Sprints training (20 min (1 min sprint, 1 min walk) -- repeat 10 intervals).

I've noticed an increase

in weight loss and muscle definition, and an increase in sex drive.

On the other hand I am exhausted all the

time and feel like not talking to much or even having the energy sometime.

Does anyone else do this training?

I find with aerobics I don't lose weigh as effectively and this is much better.
