Dynamic Activity Scaling

Actionable Target Outputs

Tools leverage lean-mass calibrated models like Katch-McArdle to eliminate estimation errors common in generic calculators.

Calculations factor non-exercise activity thermogenesis alongside structured resistance training duration.

Outputs generate specific numerical parameters rather than wide ranges, simplifying daily nutrition and gym implementation.
