🥵 Why always training too hard might limit long-term process

High-intensity functional workouts like AMRAPs, EMOMs, and “for time” efforts are often performed at a competition-level intensity. Many people who train in CrossFit or similar styles push themselves to this very high relative intensity 4-5 times a week.

While training intensely is obviously extremely important for high-power output sports like CrossFit, it might not be the best idea to ‘always’ train at intensities near max effort.

For sustainable improvement, adding lower-intensity training could be key. Why? In workouts like for instance “Fran,” performance relies heavily on how fast your body uses and then restores phosphocreatine (PCr), a quick energy source.

Recovery of PCr depends on your body’s ability to use oxygen to replenish ATP, the energy currency for all cells.

Lower-intensity exercise, especially at higher volumes, encourages capillary growth—small blood vessels that support faster oxygen supply and hence PCr recovery.

Think of it like a Toyota Prius: no matter how hard you press the pedal, there’s a limit. To go faster over the long haul, you need a bigger engine—just like you need a stronger aerobic base for lasting performance.
