paul, ever taken those brown capsules of Ephedrine, Caffeine and aspirin?

Used to take them before a session back in the day...

Also going back in the day when I was studying for my Sports Science degree I remember reading some studies of Caffeine being an ergogenic aid. Basically it has also been shown to increase the release of fatty acids into the blood stream during exercise.

So basically grab a strong black coffee before that long cardio session and you will increase the amount of fat burnt.

There you go Stu, I did promise to look in and contribute!

I hope I remembered correctly or the studies aren't now disputing the earlier findings

P.S I love Muller lite yogarts, get a pure orange lolly and dip that in a Vanilla one for an awesome little after dinner treat.
