Common Mistakes to Avoid

Cutting too much weight too fast

Rapid cuts exceeding 5% of body weight in under a week severely impair reaction time, power output, and VO2max. Start cutting 8-12 weeks out for any cut exceeding 5 kg.

Ignoring lean body mass preservation

Aggressive caloric deficits (>1000 kcal/day) cause muscle catabolism. Maintain protein at 2.2-2.8 g/kg of lean mass and include resistance training throughout the cut.
