i have a question regarding your thread about burning fat.. i am a big fan of intervel cardio this is how i start my cardio 6 mins of warm up by slowly jogging and increasing the speed every min.. then after 6 mins of warm up i do 1 min of sprinting fast running i.e speed 10 on the trade mill after that i bring it down to 7.5 for three mins then jack it up at 10 and follow the same procedure 3 or sometimes when i feel good 4 times and then finish it up with 6 mins of cool down to stabilize my heart rate.. do you think the study you presented in your thread of ' 30 mins of cardio with a 20 mins of break and then doing 20 mins of cardio' has far greater results than what i do?? i am definetly going to give this study a try starting from today.
