1. Fast vs Slow
How good are you?

2. SLOW Fibers = Endurance
FAST Fibers = Expolsive

11. Bursts of intense contractions (Hypertrophy) Fatigue easily
ANAEROBIC
Bursts of intense contractions (Hypertrophy)
Fatigue easily
*Train by increasing intensity, decreasing reps.

12. Aerobic
Anaerobic threshold: If muscle demands stay below supply needs, will stay aerobic.
If increased need, shift to anaerobic.
*Train increase reps, decrease intensity.
