Heart-rate training zonesFive zones from your own resting rate, not a formula that ignores your fitness.
Daily energy and proteinWhat a day actually costs you, and how much protein supports the training on top.
Body compositionBody fat from a tape measure, and the fat-free mass index that actually tracks your training.
One-rep maxYour working maximum as a range, from two formulas that disagree — plus the percentages to train off.
