Most high school athletes work hard all summer, show up to the first game strong and fast, and then stop lifting once the season starts. Practices get longer, homework piles up and the weight room feels optional. By the playoffs, many of those athletes are noticeably weaker than they were in week one, right when the games matter most.

It doesn't have to go that way. Strength fades slowly when you stop, but it fades. The good news is that it takes far less work to keep strength than it took to build it. Two short, focused sessions a week are usually enough to hold most of what you gained in the off-season, and sometimes to keep improving.

Why in-season lifting matters

A season is a long grind of practices, games and travel. Muscles and tendons that stay strong handle that load better, and athletes who keep lifting tend to feel fresher late in the year than those who stop. Strength also supports speed: a quicker first step and a higher jump both depend on how much force you can put into the ground.

The goal in-season is different from the off-season. You're not chasing personal records. You're trying to keep your strength and power while staying fresh for games. That changes how you pick exercises, how many sets you do and how hard you push.

The rules of in-season training

• Lower the volume, keep the intensity. Do fewer sets and reps, but keep the weights moderately heavy. Heavier, low-rep sets maintain strength without leaving you sore.
• Leave reps in the tank. Finish every set feeling like you could have done two or three more. No grinding, no failure sets.
• Time it around games. Lift early in the week, ideally 48 hours or more before a game. Avoid heavy leg work the day before competition.
• Keep it short. 30 to 40 minutes is plenty. A short session you actually finish beats a long one you skip.
• Expect some soreness at first. If you haven't lifted in a few weeks, start lighter for the first session so it doesn't affect practice.

A simple 2-day in-season plan

This template works for most field and court sports. Adjust the exercises for your sport and your coach's guidance. Rest 2 to 3 minutes between heavy sets.

Day 1 (early in the week)

1. Box jump or broad jump: 3 sets of 3. Full rest. Focus on landing softly and quietly.
2. Trap bar deadlift or goblet squat: 3 sets of 3 to 5 at a weight that feels challenging but smooth.
3. Push-up or dumbbell bench press: 3 sets of 6 to 8.
4. Single-arm dumbbell row: 3 sets of 8 per side.
5. Side plank: 2 sets of 20 to 30 seconds per side.

Day 2 (two or three days later)

1. Medicine ball throw (chest pass or rotational): 3 sets of 4 per side.
2. Rear-foot elevated split squat: 2 to 3 sets of 5 per leg.
3. Romanian deadlift: 2 to 3 sets of 6.
4. Pull-up or band-assisted pull-up: 3 sets of 4 to 8.
5. Dead bug: 2 sets of 8 per side, slow and controlled.

If you have a game on Friday, Monday and Wednesday work well. With two games a week, lift once right after the first game's recovery day and keep the second session light, or drop it that week.

Adjusting for your sport

Collision sports like football and hockey should keep neck, upper-back and shoulder work in the plan. Bodies take a beating in games, so keep lower-body volume modest.

Running sports like soccer and cross country already pile up leg work in practice. Keep the lower-body sets low and include hamstring work such as Romanian deadlifts or Nordic curls, with a coach's guidance.

Jumping sports like basketball and volleyball get plenty of jumps in practice. You can often skip extra plyometrics and focus on strength and landing control. You'll find sport-specific progressions in our basketball training programs.

Throwing and racket sports like baseball, softball and tennis should keep a short arm care routine (bands for the rotator cuff and shoulder blades) in every week.

How to know if it's working

You don't need fancy testing. Write down your weights each session. If you can lift about the same load for the same reps in week eight as you did in week one, you've maintained your strength. That's a win. Also watch how you feel: legs that feel springy on game day mean the timing is right. Legs that feel heavy mean you should lift earlier in the week or trim a set.

Recovery is part of the plan

In-season training only works if recovery keeps up. Teenagers generally do best with 8 to 10 hours of sleep a night. Eat real meals with a protein source at each one, and have a snack after practice instead of waiting until a late dinner. Drink water through the day, not just at practice. One full day off each week, with no practice and no lifting, helps the body and the mind reset.

Common mistakes

• Stopping completely. Even one session a week is far better than none.
• Training to failure. Exhausting sets add fatigue without adding much benefit during the season.
• Adding new, unfamiliar exercises. New movements cause extra soreness. Stick with lifts you already know well.
• Ignoring the coach. Your team's practice plan comes first. Talk to your coach about where lifting fits.

Quick answers

Will lifting in-season make me slow or sore for games? Not if you keep the volume low and lift at least two days before games. Most athletes feel faster, not slower.

Is lifting safe for high schoolers? Well-supervised strength training with good technique is widely considered safe and beneficial for teens. Learn the movements from a qualified coach and add weight gradually.

What if I only have 20 minutes? Do one jump, one lower-body lift, one push and one pull for 2 sets each. That still counts.

Finish the season stronger

The athletes who are still strong in the final weeks are usually the ones who never stopped training.
