Pre-Season Conditioning: How to Build Up Without Getting Hurt

Every fall on the North Shore, the same story repeats. Someone eases off over the summer, then the season starts and they go straight into full practices and games, and a couple of weeks later a muscle or a joint has had enough. It looks like bad luck, but most of these injuries come from a pattern we can see coming: doing too much too soon after an off-season of doing too little.

Why the first weeks of a season are risky

The off-season is not the problem by itself. The problem is the contrast. If you spend the summer doing little and then start a fall sport at full intensity, your body faces a large, sudden increase in load right when it is least prepared for it. Muscles, tendons, and bones all adapt to load, but they adapt slowly, and they cannot catch up in a single hard week.

This is why the first two or three weeks of a season see so many injuries. The player feels motivated and pushes hard, but the tissues have not built the capacity to handle that push yet. A conditioning block done before the season starts closes that gap, so the first hard practice is not the first hard thing the body has done in months.

The too much too soon problem, explained

There is a helpful way to think about training load. Your body cares less about how much you do on a single day and more about how that compares to what you have been doing recently. A week that is only a little harder than your recent average is usually fine. A week that is far harder than your recent average is a spike, and spikes are where the risk climbs.

Training load research made this idea popular with the acute to chronic workload ratio, which compares a recent week of load against the average of the previous few weeks, and found the lowest injury risk when the two are reasonably close rather than the current week being far higher. It is worth being honest that the researchers themselves have since stepped back from the strongest claims, so this is a useful guiding idea rather than an exact formula to obey. The plain-English version still holds: big jumps in load raise risk, and gradual builds protect.

How a gradual build actually works

The fix follows directly from the problem. Instead of arriving at the season unprepared, you raise your load in steps over several weeks so each week is only a bit more than the last. This gives your muscles, tendons, and bones time to adapt and get stronger before the season demands full intensity.

A sensible pre-season block starts well before the first game and builds fitness, strength, and sport-specific work in stages. The details depend on your sport and your starting point, but the principle is the same one we use when bringing someone back from injury, where we progress by meeting targets rather than rushing. We describe that step-by-step logic in our guide to criteria-based return to sport.

What conditioning does besides fitness

It is easy to think of conditioning as just getting fit, but the more important part for injury risk is building tissue capacity. Stronger muscles and tendons can absorb more load before they fail, and a body used to running, cutting, and jumping handles those movements more safely than one that has not done them in months.

Structured programs add to this. Warm-up and neuromuscular routines such as the FIFA 11+ program have been shown in reviews of randomised trials to reduce injuries in soccer players by around 30 percent. That is a meaningful effect from something as simple as a consistent, well-run warm-up and strength routine done regularly. These programs work partly by preparing the body and partly by improving control during the fast, unplanned movements that cause many injuries. The same thinking helps specific injuries, such as the eccentric strength work we cover in our piece on hamstring strain rehab for soccer and rugby.

Where screening fits

Before building a conditioning plan, it helps to know where your gaps are. Movement screening is a check of how you move, balance, and control force during sport-relevant tasks. It can reveal weaknesses, large differences between your left and right sides, or movement patterns worth improving.

A screen is not a crystal ball. It does not predict with certainty who will get hurt, and it should not be sold that way. What it does is give a starting point, so the conditioning block targets your specific gaps rather than being a generic routine. A player with a weak, poorly controlled hip needs different work than one with limited ankle movement, and screening is how we tell the difference.

North Shore timing for fall sports

Local fall sports, from soccer and field hockey to rugby and the start of the hockey season, tend to ramp up quickly once school and clubs return. That timing is exactly why the summer-to-fall jump catches so many people. If you know your season starts in early September, starting a gradual build a few weeks earlier gives your body the runway it needs.

This matters just as much for the parents of young athletes as for adults. A teenager who grew over the summer and did little activity can face a large jump in load at the first practices, and that combination deserves attention rather than being ignored until something hurts.

If you left it late

Not everyone reads this in July. If the season is close and you have done little to prepare, the plan changes but there is still value in doing something. The key is to resist the urge to cram, because a rushed catch-up is the exact spike that raises risk. A careful, gradual build from where you actually are now, even over a shorter window, is safer than trying to force months of missed preparation into a single week.

When to get assessed

If you are heading into a fall season and you know you did little over the summer, if you have a history of the same injury coming back each season, or if you want a conditioning plan built around your sport rather than a generic routine, an assessment is worth it. We screen how you move, find the gaps that matter, and set a gradual build that fits the time you have before your season starts.

Book a 30-minute appointment and we will assess where you are, screen your movement, and build a pre-season plan that raises your load safely so you start the season ready rather than playing catch-up.
