High intensity cardiovascular (sprint) training is far more effective to get lean (if that is your goal) than long, steady-state cardiovascular training. It can also boost testosterone levels, therefore, increase sex drive due to the fact it can put your body into a more anabolic state, compared to long steady-state cardiovascular training.
So what are the top 10 ten reasons for doing it?
1- It can be done within 15-30 minutes, which is less stressful on the body.
2- You can get fit very quickly, as you are always pushing the speed and/or level up at every interval.
3- It brings on a good sweat in a very short period of time, which is good for de-toxing the body.
4- It does not put you in as much of a catabolic state as with most cardiovascular programmes.
5- It will keep you more focused, as you are always trying to beat your previous speed/level from interval to interval.
6- It can be done on any type of cardiovascular equipment.
7- You can vary the interval times to suit your fitness level.
8- You can have the “active resting” speeds/levels (the low points on the graph), to suit your fitness level.
9- You can vary the “on” phase speeds/levels (the high points on the graph), to suit your fitness level.
10- It’s more fun and it will get you far more lean!
