Hitt bro 15minutes post work out for fat burn is the way to go, you use up all your glycogen storage while lifting so once you hit up the cardio all your body has to use for energy is fat! I do it in intervals like this:
Interval 1: 3 mins moderate pace, normal speed..
2. 2 mins: Set the resistance so that you can barely make the machine move..
3. 3 mins: Go at a super fast speed...
4. 3 mins: Set the resistance so that you can barely move the machine.
5. 1 min: Superfast speeds
Cooldown: 5 mins at normal speeds and resistance levels...
you can apply this to anything you do, I for example will do the elliptical one day, bike the next, treadmill the day after and if im feeling really ambitious I'll hit up the jump rope. shit is killer that way but fantastic for calves! lately ive been doing this with the addition of forged burner which in IMO is one of the best if not the best fat burners out. Great appetite supression clean energy, intense focus and sense of well being plus a strong thermo effect!
