No Boring Cardio!

Okay-
Most of us just go every morning, jump on the tread mill and start running or walking at a constant speed for the next 20-30 mins. Then we jump on the cycle or cross trainer and do the same.
STOP! That is not the way if you want weight loss or endurance.
Your body will adjust and moreover your heart beat remains almost constant- so where is the 'CARDIO'-vascular work out.
For weightloss- the only way to go is interval training cardio. This is mostly advised by good health experts and all athletes and sportsman follow this.
Interval training means- stress out your body in intervals. So the next time you jump on a tread mill instead of a boring 20 min run/walk y dont u try this-

1) walk at speed 6 got a minute(just for warm up)
2) run at speed 9 for 1 minute
3) run at speed 12.5 for 1 minute
4) run/walk at speed 8.5 for 1.5 min
5) run at speed 14-15 for 1 to 1.5 min

repeat steps 2-5 for 20-30 mins. Now, I have mentioned the speeds according to my speed levels. adjust according to your fitness. If you are just starting you wont be able to run at 14-15 for 1.5 min, so reduce it accordingly.
Follow similar pattern on cycle or cross trainer.
This is the only way to go for cardio. Keep improving your speeds as you get fitter. This leads to more fat burn rather than running at constant speed, although machine may show same calorie loss.
Follow this and notice the diff.
Also- this maked your cardio interesting! you get to change speeds now and then. You wont know how those 25 mins go by.

weight training is also necessary for fat loss. More on that laterz. Queries? lemme know.
