Caffeine is less work?
14:14 Sunday 25 Nov 07
Caffeine makes the heart beat faster. So doing a cardio workout after having drunk something like Red Bull means you actually work less hard because the cardio target is a certain rate (143 for me) and the drink has got you part of the way there already. I think. So in order to really workout harder I should have a soothing mug of Horlicks first, yes? (Not that I go by rate of heart, I go by BPM from Podrunner. Today a 140 is in order).
Post-workout update:
Yesterday. 131 BPM music. 58:26 I hit 1000 calories
Today. 142 BPM. At 58:26 I hit 922 calories.
Ignoring the fact it says calories (which may or may not be accurate) the fact is the number is 78 calories less. Doesn’t seem a lot but it’s a few minutes work.
I’d drunk the equivalent of just over 2 cans of Red Bull.
I suppose I need to do the 142 again.
And yes I know it could be something else too, but it’s a genuine question.
