Thanks for the input so far guys.
I'm 20 years old, weigh 10 stone 8 and am 5'7 tall. I don't have a huge amount of noticable fat on me, just a little bit around the waist and would like to firm my pecs up a bit. My diet's pretty good, I rarely snack on junk food. Have cereals, fruit/veg every day, good healthy meal each night of some kind of meat, veg and carbs. I've started to drink lots more water too, gone from about 1-2 pints a day to 4-5 pints.

I definately see what you mean about rowing for 10mins not being sufficient to burn the daily calories. Maybe I should find a new sport which doesn't bore me when exercising for 30-40mins at a time. I'm not really interested in weight training at a gym, I just want to get a bit more definition and generally fitter!

I'll try the Tabatas...never heard of it until now! Cheers
