How do you maximize your cardio workout sessions? It's super simple actually!
You want to have your heart pumping so much that you can only get 2 or 3 words out before sucking in air. If you are able to have a conversation with ease, you're running too slowly! Pick up the speed and push yourself until you're breathless, which is your anaerobic threshold. This is when your body stops using oxygen to fuel your muscle and actually starts burning carbs instead (can I get an Amen!?).
So what's the best way to melt that fat? Have short intervals of running at a fast speed added to your jog. After getting warmed up, try to sprint (somewhere between 6 and 8.5 on the treadmill) at a speed that literally makes you breathless. Hold this speed for 30-60 seconds (try to eventually work up to a full minute at that speed) and then slow it down and jog or walk it out for one minute (3.5 to 4.5 on the treadmill). Repeat this 10 times and say "so-long" to fat!
