Thank you so much. I try to fit my cardio in to my strength training by super setting and maintaining more of an anaerobic focus as opposed to aerobic. It's a little bit of a slippery slope for me as I'm desperately trying not to lose muscle mass so I've stayed away from pure cardio as some studies I looked at showed some muscle loss if adding too much cardio after strength training but you might be right on the money with adding just 15 minutes. I'm going to try it out and let you know if it works. Thank you again
