Common Mistakes to Avoid
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.
