Phil Daru from Marek Health joins Brendan Schaub and Bryan Callen on The Fighter and The Kid to break down Khamzat Chimaev’s cardio issues, fighter mentality, overtraining, Bo Nickal’s wrestling-heavy style, concussion damage, sports-specific training, and the science behind elite UFC performance.

Phil Daru has trained world champions across UFC, boxing, bare knuckle fighting, and professional sports, and explains what separates elite fighters from great athletes — including recovery, strength & conditioning, weight cuts, endurance, mobility, and mental toughness.

The crew also discusses Sean Strickland, Khabib’s pressure style, football injuries, combat sports psychology, and why some fighters mentally break under pressure.
