Also have started doing about 15-20 minutes daily cardio after my workouts to shed remaining fat hoping to see my abs a lot more than I can now. I feel like 15 mins. of cardio a day is better for myself personally because I'm just starting now after not running a single lap since I was in prison and still only ran for like half a summer. Point being anymore than a good paced 15ish minutes on the treadmill then possibly some stepmill a day is plenty for me and results will show I'm sure
