Although you will probably start feeling better and stronger immediately, new students can expect about a 15-20% improvement in strength and endurance following the first fifteen sessions. In addition, our findings show that flexibility, agility and body composition are improved. Subjective things like increased mental toughness, energy levels, improved sleep and reduced joint stiffness are also reported. Most of our students are shocked at their improvements even though they would consider themselves exercisers before starting CrossFit.

Overtraining for long periods of time is bad. Short-term, planned overtraining, however, can be a massively powerful tool.
Functional overreaching is essentially short-term overtraining where you have a goal of digging yourself into a recovery ditch. You intentionally push your training past your body’s ability to recover before backing off, super-compensating, and jumping out of that recovery hole to new levels of strength and muscle. Doing so allows you to benefit from the harder training as your body gets a chance to recover.
