How to Pick Your… Pre- Workout

Caffeine is your key word. No other stimulant will supercharge brain and body like it. A pre-training dosage of 150 to 300mg will turn up the dial without blowing a fuse. ‘Any more than 400mg and you’re heading down silly street,’ says Amico. For full impact, don’t take your pre-workout at the start of your session or you’ll peak too late – 30 to 45 minutes beforehand should do it.

Chapman is also a fan of beta-alanine, ‘which basically works as an acid buffer’, protecting your muscles against The Burn. Branched-chain amino acids (BCAAs) are another common extra, delaying fatigue while supporting muscle function. Keep an eye out for added creatine if you’re already dosing separately.
