Re: Tips to increase energy and endurance?
A tip that has worked for me is to take my waking pulse each morning. If it goes up or down ten percent of normal, I cut back on exercise that day. I learned to do that while playing around doing triathlons some time ago. Also there is a danger to over-exercising as well; you sometimes will tax your immune system and end up catching every bug you come in contact with. YMMV.
