so when i go to the gym i tend to end up doing an hour of cardio and then aabout 40 mins on toning machines/weights etc.

the only cardio i feel is doing anything for me is the rowing machine.

ive read about doing high intensity in short bursts but then ive read about different types of HIT in different types of short intervals.

i dont have a problem with controlling my food intake when i exercise if anything im more conscious so i know its worth me doing exercise.

i do most of my cardio on a bike but i find myself just sitting there getting a bit lazy watching the tv screens.

id like to do more on the rowing machine but again im not sure how i should do it. should i do like a min of hard rowing then 30 second rest? or keep increasing the minutes with a 30 second rest in between?

any advice would be much appreciated
