The Peak 8 routine it will quickly raise your heart rate 8 times for very short bursts, with a cooling down period in between. Ideally you’ll be sprinting or cycling full throttle for 30 seconds with a 90 second cool down in between each outburst.
This is the fastest way to lose fat and build muscle in the body. Peak 8 actually stimulates the growth hormone in the body. I personally feel that it is one of the best ways to exercise, especially considering the speed at which you can lose fat and build muscle (build muscle if you do strength training)
What you eat after Peak 8 training does matter
It’s recommended that you do not eat sugar or carbohydrate for 2 hours after the Peak 8 exercise because these foods can impact the release of the growth hormone in the body.
Figure your heart rate by this formula
deduct your age from 220 that number is your maximum heart rate! what you should try to get is 65%- 85% of your maximum heart rate. i suggest buying a heart rate monitor it costs about $30.00. google peak 8
You burn 30 percent more fat from doing cardio after a weights session as opposed to cardio on its own.
Before doing anything get the OK from your doctor!!!
High intensity intervals (go all out for about a min then go slow for like 30-45 seconds) I'd try it on a stationary bike
