When competition season begins, athletes often make one of two mistakes: they stop strength training altogether, or they continue training exactly the way they did during the off-season.
Neither approach is ideal.
Once practices, games, tournaments, travel, school, and other responsibilities fill the calendar, your training needs to change. In-season training is not about trying to build as much strength as possible or setting new personal records. It is about maintaining the physical qualities you’ve worked hard to develop while keeping your body prepared for competition.
A well-designed in-season training program can help athletes maintain strength and power, address weaknesses, support injury prevention, and stay physically prepared throughout a long competitive season.
What Is In-Season Training?
In-season training is the strength, conditioning, mobility, and performance work an athlete performs while actively competing in their sport.
The goal is different from off-season training.
During the off-season, an athlete typically has more time and energy available to focus on building strength, improving speed and power, developing movement quality, and addressing larger performance limitations.
During the season, the athlete is already receiving a significant training stimulus from practices, games, competitions, and sport-specific work.
That means the gym should support the sport rather than compete with it.
Instead of asking, “How much training can I handle?” the better question is:
“What training will help me perform at my best without creating unnecessary fatigue?”
Why Should Athletes Train During the Season?
Stopping strength and performance training when competition begins may seem logical, especially when an athlete already feels busy and tired.
But playing a sport does not necessarily replace a well-structured strength program.
1. Maintain Strength and Power
The strength and power an athlete develops during the off-season still need to be maintained.
In-season training provides a stimulus that helps athletes preserve important qualities such as:
- Lower-body strength
- Upper-body strength
- Explosive power
- Core stability
- Single-leg strength
- Movement control
- Muscular endurance
The objective isn’t necessarily to become dramatically stronger during the middle of a competitive season.
The objective is to avoid losing the physical qualities that help you compete.
2. Support Injury Prevention
Competition creates repetitive demands on the body.
Depending on the sport, athletes may repeatedly sprint, jump, cut, throw, swing, change direction, absorb contact, or perform the same movement patterns hundreds of times throughout a season.
A thoughtful strength program can help address areas that may not receive enough attention during normal practices.
For example:
- Baseball players may need additional shoulder, elbow, and rotational work.
- Soccer players may benefit from hip, groin, hamstring, and ankle-focused training.
- Basketball players may need continued single-leg strength and landing mechanics.
- Hockey players may need additional hip, groin, and rotational strength.
- Overhead athletes may require consistent shoulder stability work.
The goal is not to add more fatigue. It is to make the training more targeted.
3. Maintain Movement Quality
Athletes don’t just need to be strong. They need to be able to use that strength effectively.
Mobility and stability work can help athletes maintain quality movement throughout a long season.
Areas such as the hips, ankles, shoulders, thoracic spine, and hamstrings may require additional attention depending on the athlete and sport.
Even a short mobility routine can be valuable when performed consistently.
4. Stay Prepared for the Entire Season
A season can last for months.
An athlete who feels great during the first few weeks but becomes increasingly fatigued, weak, or beat up as the season progresses may struggle when the most important competitions arrive.
In-season training should help athletes maintain their physical foundation throughout the entire competitive calendar—not just survive the first few weeks.
How Should In-Season Training Change?
The biggest difference between off-season and in-season training is training stress.
During the off-season, athletes have more room to accumulate training volume.
During the season, practices and competitions already contribute significant stress.
Your strength program should account for that.
Focus on Quality Over Quantity
In-season workouts generally don’t need to be long.
A focused session can address the most important movement patterns without leaving an athlete exhausted.
A well-rounded program may include:
- Squat or knee-dominant movement
- Hinge or posterior-chain movement
- Push
- Pull
- Single-leg exercise
- Core or trunk training
- Sport-specific accessory work
The exact exercises, sets, repetitions, and intensity should depend on the athlete.
Adjust Training Around Competition
There is no universal in-season schedule that works for every athlete.
A soccer player with one game per week has a very different workload than an athlete playing three games in four days.
Training needs to account for:
- Number of practices
- Number of competitions
- Game intensity
- Travel
- Tournament schedules
- Athlete age
- Position
- Current fatigue
- Injury history
- Individual recovery capacity
The harder the competition schedule becomes, the more important it is to manage training volume and recovery.
Don’t Chase Personal Records
In-season training isn’t the time to constantly test one-rep maxes or turn every workout into a competition.
An athlete may still make strength gains during the season, but performance goals should be balanced against the demands of the sport.
If a workout leaves an athlete so sore or fatigued that practice performance suffers, the program needs to be adjusted.
How Often Should Athletes Train In-Season?
For many athletes, two focused strength sessions per week can provide a strong foundation for maintaining strength and athleticism.
Some athletes may benefit from more frequent training, while others may need less depending on their competition schedule.
The key is not simply counting workouts.
The key is managing the athlete’s total workload.
Two quality sessions that complement the sport can be more effective than four sessions that leave an athlete constantly fatigued.
Recovery Is Part of the Training Program
Recovery should not be treated as something athletes do only after everything else is finished.
It is part of the program.
During the season, athletes should pay attention to:
- Sleep
- Nutrition
- Hydration
- Mobility
- Rest days
- Practice and competition volume
- Overall fatigue
Sometimes the best decision is a training session.
Sometimes the best decision is a lighter session.
And sometimes the best decision is to recover.
Good coaching means knowing the difference.
Signs an Athlete May Need to Adjust Their Training
Athletes and coaches should pay attention to changes in performance and recovery.
Potential warning signs include:
- Persistent soreness
- Declining performance
- Unusual fatigue
- Decreased motivation
- Poor sleep
- Repeated minor aches
- Slower recovery between practices
- Decreased strength or explosiveness
- Feeling consistently “heavy” or sluggish
One bad day doesn’t necessarily mean the program needs to change.
But consistent changes should not be ignored.
The Bottom Line
In-season training should make athletes better competitors—not simply more tired athletes.
The goal is to maintain strength, power, mobility, stability, and movement quality while managing the physical demands of practices and competition.
That requires a different approach than off-season training.
Train with purpose. Adjust the workload. Prioritize recovery. And make every session serve the bigger goal: performing at your best when it matters most.
