Episode notes
Rapid Progress Example From Coaching
- Steve described a client who rapidly added 50+ lb to his total within weeks after junior nationals.
- Such stories illustrate large inter-individual variance and the power of optimistic belief.
Creatine's Immediate Versus Cumulative Effects
- Creatine often produces an immediate size bump via cell water, but long-term training effects may not differ substantially.
- Short-term saturation may give transient performance boosts rather than magnified longitudinal growth.
Keep Taking Creatine
- Continue using creatine: it's cheap, safe, and likely provides small but real benefits.
- Rely on research rather than subjective feeling to judge creatine's impact on your training.
