Episode notes
Prioritize Resistance And Protein
- Prioritize progressive resistance training and high protein to preserve muscle during large deficits.
- Do minimal but intense resistance work rather than lots of aerobic exercise during RFL.
Aerobic Can Hastens Downregulation
- Excessive aerobic activity during a large deficit accelerates reductions in energy expenditure.
- Aerobic work burns little relative to big deficits and can worsen adaptive responses.
Use Machines To Monitor Muscle
- Use machine and isolation exercises as reliable performance proxies when compounds drop due to leverage changes.
- Track leg extensions or preacher curls to monitor true muscle maintenance.
