Contrary to common belief, caffeine is not something you become tolerant to, you are simply either receptive to it or you aren’t…simple as that. Even if you’re a habitual coffee drinker (a high source of caffeine), caffeine’s effects are not dampened down or reduced.
Quick caffeine test…
Ask yourself this question… ‘If you were to consume caffeine after 5pm, would you have any trouble sleeping’? If the answer to this question is yes, then you are probably receptive to caffeine’s effects, if the answer is no, then lo and behold your probably not. Caffeine, like many drugs have responders and non-responders, it’s as simple as that.
If you deem yourself to be a responder and would like to consume caffeine as an ergogenic aid (training aid), then aim to consume approx 3mg/kg body weight prior to your session.
