Training Methodology
Preseason Conditioning
Preseason conditioning refers to the structured physical preparation phase that bridges a program’s offseason training and the start of the competitive season. The goal is to prepare athletes for the specific physical demands of their sport’s practice and competition schedule while managing the transition from general strength and conditioning work to sport-specific load. Done well, preseason conditioning produces athletes who arrive at the first competition physically prepared and healthy. Done poorly, it produces a wave of early-season overuse injuries, burnout, and athletes who peak in August instead of November.
The transition problem
The most common mistake in preseason conditioning is treating it as a fitness test rather than a preparation phase. Coaches who dramatically spike training volume or intensity in the first week of preseason, whether through excessive running, two-a-days without adequate recovery, or abrupt increases in contact and sport-specific loading, are asking athletes’ bodies to absorb stress they have not been progressively prepared for. The Acute:Chronic Workload Ratio framework makes this explicit: any time the training load in a given week significantly exceeds the athlete’s chronic baseline, injury risk rises. Preseason is the highest-risk period of the year for this because the transition from summer training to full practice volume happens quickly.
What good preseason conditioning looks like
Effective preseason conditioning builds from the offseason base rather than abandoning it. The first one to two weeks should prioritize acclimatization, especially in hot weather, with gradually increasing volume and intensity rather than maximal effort from day one. Conditioning work should reflect the actual energy system demands of the sport: interval-based work for football, more aerobic base for soccer and cross country, repeated sprint formats for basketball and lacrosse. Strength training volume typically decreases as practice volume increases, not because strength stops mattering but because the total training load has to be managed. Coaches who maintain full offseason lifting volume on top of two-a-day practices are stacking too much stress onto athletes who are already absorbing significant new loads from practice.
Heat is the variable coaches most often underestimate
Summer preseason in most of the country means training in heat and humidity that athletes have not been exposed to consistently during the school year. Heat acclimation takes seven to fourteen days of consistent exposure to develop meaningfully. Building the first week of preseason around lower intensity and monitoring WBGT thresholds allows athletes to acclimatize before full-intensity work begins. This is not softness. It is how you keep athletes healthy enough to actually train through the season.
