Strength & Conditioning for Teenage Athletes (13–18)

If you’ve ever watched your teen get pushed off the ball, fade late in games, or deal with the same sore knee every season… you’ve probably thought: “Do we need a real strength program?”

You’re not alone. Most parents want the same things:

  • Better performance (speed, power, confidence)
  • Fewer injuries
  • A plan that fits school, practice, and games
  • No “gym bro” nonsense that beats kids up

This guide breaks down strength and conditioning training for young athletes ages 13–18 in plain language. You’ll get programming rules, the best strength exercises for teenagers, sample set/rep plans, and how to lift during the season without running your kid into the ground.


Strength and conditioning training for young athletes: what it really means

“Strength and conditioning” is just training that helps sports.

  • Strength = how much force your teen can make (think: holding position, driving through contact, stopping fast).
  • Power = strength used fast (think: jumping, sprinting, quick first step).
  • Conditioning = the engine (think: repeat sprints, staying sharp late in games).
  • Mobility = moving well through a full range (hips, ankles, shoulders).
  • Skill = sport practice (still the main thing).

A good plan blends these so your teen is more athletic, not just tired.

If you want the big-picture roadmap, our parent-friendly breakdown of Long Term Athlete Development (LTAD) explains why the “right training at the right time” matters.


Is lifting safe for teens? What the research says

Yes—when coached and progressed well.

A major position statement from the National Strength and Conditioning Association (NSCA) says youth resistance training is safe and effective and can improve strength, performance, and injury resistance when properly supervised and programmed. It also notes that most injuries happen from poor technique, too much load, or lack of supervision, not from lifting itself.

Another widely cited review in British Journal of Sports Medicine found that youth strength training can reduce sports injuries, especially when it’s part of a well-rounded program.

The big rules for a teen athlete workout (13–18)

Here are the “parent sanity checks” I use.

Technique beats weight—always

A rep (one lift) only counts if it looks right. If form breaks, the set is done.

Simple coaching cue: “Smooth reps, full control, no grinding.”

Progress slowly (and it still works)

Most teens don’t need max lifts. They need practice and steady progress.

A good goal: add 2.5–10 lbs to a lift every 1–2 weeks if form stays clean.

Train the whole body, not just “mirror muscles”

Sports are full-body. Your teen needs:

  • Legs (squat patterns)
  • Hips (hinge patterns)
  • Upper push (push-ups/press)
  • Upper pull (rows/pull-ups)
  • Core (anti-rotation, bracing)
  • Single-leg work (balance + knee/hip control)

Recovery is part of youth athletic training

Teens grow fast. That’s stressful on the body.

Basic recovery targets:

  • Sleep: 8–10 hours (teens really need it)
  • Protein: spread across the day (more on this below)
  • Easy days: at least 1–2 per week depending on sport load

Best strength exercises for teenagers (simple, effective, coach-friendly)

You don’t need fancy stuff. These are staples because they build strength safely and carry over to sports.

Lower body: squat and single-leg strength

  • Goblet squat (great first squat)
  • Front squat or trap bar deadlift (when ready)
  • Split squat or rear-foot elevated split squat (great for soccer, basketball, lacrosse)
  • Step-ups (knee-friendly when done right)

Hips: hinge strength (posterior chain)

“Posterior chain” just means the backside—glutes and hamstrings.

  • Romanian deadlift (RDL) with dumbbells or bar
  • Hip thrust or glute bridge
  • Kettlebell deadlift (good learning tool)

Upper body: push + pull balance

  • Push-ups (weighted later)
  • Dumbbell bench press (often easier on shoulders than barbell)
  • 1-arm dumbbell row
  • Pull-ups or assisted pull-ups
  • Cable row or band row

Core: bracing and control (not a million crunches)

  • Dead bug
  • Side plank
  • Pallof press (anti-rotation)
  • Farmer carry (great “sport core”)

Jumps, sprints, and throws (power)

Power work should be low volume and high quality.

  • Box jump (safe landing focus)
  • Broad jump
  • Medicine ball chest pass or rotational throw
  • Short sprints (10–30 yards)

For sprint progressions by age, check our speed training guide for youth athletes.


Sets, reps, and intensity for teenage athletes (what actually works)

Parents often ask, “How many sets and reps should my teen do?”

Here’s a practical framework used in many youth athletic training programs and supported by youth resistance training research and coaching consensus.

For beginners (new to lifting or inconsistent)

Goal: learn patterns, build consistency.

  • 2–3 days/week
  • 2–3 sets of 6–10 reps
  • Leave 2–3 reps in the tank (don’t max out)
  • Rest 60–120 seconds

Example lifts: goblet squat, RDL, push-up, row, split squat, dead bug.

For intermediate teens (6+ months of solid training)

Goal: get stronger and more powerful.

  • 2–4 days/week
  • Main lifts: 3–5 sets of 3–6 reps
  • Accessories: 2–4 sets of 6–12 reps
  • Rest 2–3 minutes on main lifts

For advanced high school athletes (well-coached, 2+ years)

Goal: strength + power while managing sport stress.

  • 3–5 days/week depending on season and sport
  • Strength: 3–6 sets of 2–5 reps
  • Power: 3–6 sets of 1–3 reps (jumps/throws/sprints)
  • Conditioning tailored to sport (not random punishment)

Important: Advanced doesn’t mean “lift heavy all the time.” It means better technique and better planning.


Periodization around sport seasons (so your teen isn’t cooked)

“Periodization” is a fancy word for planning training in phases. The goal is simple: build in the off-season, maintain in-season.

Off-season: build strength and muscle (and fix weak links)

This is where strength gains happen.

  • 3 days/week lifting for most teens (some can handle 4)
  • Add some conditioning, but don’t let it crush lifting progress
  • Focus on:
    • Squat/hinge strength
    • Single-leg control
    • Upper back strength (posture + shoulder health)
    • Power basics (jumps/throws)

Pre-season: turn strength into sport speed

Now we keep strength but shift toward power and conditioning that matches the sport.

  • 2–3 lifts/week
  • More:
    • Sprints
    • Jumps
    • Change of direction
    • Repeat-effort conditioning (short bursts, short rest)

In-season: maintain strength, protect the body

In-season is about staying strong and fresh.

  • 1–2 lifts/week
  • Lower volume (fewer total sets)
  • Keep intensity moderate-to-high (so strength doesn’t drop)
  • Avoid “new exercises” that cause big soreness

A lot of families do best with a simple structure:

  • Day after game: light recovery lift (20–35 min)
  • 2–3 days before next game: heavier strength lift (35–55 min)

For more age-appropriate templates, see our youth athlete training program plans.


Two real-life scenarios (because every family’s schedule is different)

Let’s make this practical.

Scenario A: Multi-sport teen with a packed week

Think: soccer + school lifting class + weekend games.

Goal: keep them healthy and strong without adding stress.

  • 1–2 short lifts/week
  • No extra conditioning (they’re already getting it in practice/games)
  • Focus on:
    • Single-leg strength
    • Hamstrings/glutes
    • Upper back
    • Core bracing

This kind of athlete often thrives because they get variety. If your kid is younger or still building basic movement skills, mixing sports and simple movement games matters a lot—our physical literacy activities guide explains why.

Scenario B: Single-sport teen chasing a varsity spot

Think: baseball player training year-round, wants more power and speed.

Goal: build strength + power, but avoid overuse injuries.

  • 3 lifts/week in off-season
  • 2 lifts/week in pre-season
  • 1–2 lifts/week in-season
  • Add:
    • Sprint work 1–2x/week
    • Medicine ball throws 2x/week
  • Carefully manage throwing volume (for baseball) or jumping volume (for volleyball/basketball)

Sample teen athlete workout plans (with real numbers)

These are examples you can take to the gym today. Adjust loads so reps look clean.

Sample full-body plan (beginner, 2 days/week)

Day 1

  • Goblet squat: 3 x 8
  • Dumbbell RDL: 3 x 8
  • Push-ups: 3 x 6–12
  • 1-arm dumbbell row: 3 x 10/side
  • Side plank: 3 x 20–30 sec/side

Day 2

  • Split squat: 3 x 8/side
  • Hip thrust: 3 x 10
  • Dumbbell bench press: 3 x 8
  • Assisted pull-up or lat pulldown: 3 x 8–10
  • Dead bug: 3 x 6/side (slow)

Progression: when they hit the top reps with great form, add 5 lbs next week.

Sample 3-day plan (intermediate off-season)

Day 1 (Strength)

  • Trap bar deadlift: 4 x 4
  • Dumbbell bench press: 4 x 6
  • Row (cable or dumbbell): 4 x 8
  • Split squat: 3 x 8/side
  • Pallof press: 3 x 10/side

Day 2 (Power + Speed)

  • Sprints: 6 x 20 yards (full rest)
  • Box jump: 4 x 2
  • RDL: 3 x 6
  • Push-ups (weighted if ready): 3 x 8
  • Farmer carry: 4 x 20–30 yards

Day 3 (Strength)

  • Front squat (or goblet squat): 4 x 5
  • Pull-ups (assisted if needed): 4 x 4–8
  • Hip thrust: 3 x 8
  • Shoulder-friendly press (landmine or dumbbells): 3 x 8
  • Side plank: 3 x 30 sec/side

In-season “maintenance” lift (1 day/week, 35–45 minutes)

  • Trap bar deadlift or squat variation: 3 x 3
  • Bench press or push-up: 3 x 5
  • Row or pull-up: 3 x 6–8
  • Split squat or step-up: 2 x 6/side
  • Core (Pallof or carry): 2–3 sets

Keep it crisp. Leave the gym feeling better than when you walked in.


Conditioning for teenage athletes (don’t double-count practice)

This is where a lot of well-meaning parents go wrong.

If your teen has:

  • 3–5 practices/week
  • Games on weekends
  • PE class …they might already be doing plenty of conditioning.

Extra conditioning should have a purpose:

  • Build repeat sprint ability (soccer, hockey, basketball)
  • Build aerobic base (helps recovery between hard efforts)
  • Prep for tryouts

A simple add-on (off-season, 1–2x/week):

  • Bike or jog: 20–30 minutes easy
  • OR intervals: 8–12 x 15 sec hard / 45 sec easy

If speed is the goal, don’t turn speed days into “conditioning days.” Speed needs full rest to stay fast.


Nutrition basics that support strength gains (without overthinking it)

You don’t need perfect. You need consistent.

  • Protein: aim for 20–35g per meal, 3–4 meals/day (chicken, eggs, Greek yogurt, beans, beef, tofu)
  • Carbs: fuel practice (rice, pasta, fruit, potatoes, oatmeal)
  • Fluids: bring a bottle everywhere
  • Post-workout: a normal meal within 1–2 hours is fine; chocolate milk works in a pinch

Research consistently shows that adequate protein plus resistance training supports muscle growth and recovery, especially in active teens. A solid overview is here: International Society of Sports Nutrition position stand on protein


Common mistakes in youth athletic training (I see these every season)

Lifting heavy too soon

If your teen is “testing max” every week, progress usually stalls and aches show up.

Too many random workouts

One week it’s machines, next week it’s a TikTok circuit, then it’s max push-ups. The body likes a plan.

Skipping pulling and single-leg work

Lots of pressing + little pulling can irritate shoulders. Lots of two-leg lifting + no single-leg work can leave knees and hips unprepared.

Conditioning on top of conditioning

If they’re already exhausted from practice, more running often makes them slower—not fitter.

No deload weeks

A “deload” is a lighter week. Teens need these, especially during growth spurts and heavy school stress.

Simple deload: cut sets in half for 1 week every 4–8 weeks.


When to work with a certified strength coach (and what to look for)

A great coach can be a game changer—especially if your teen is new, has pain, or needs structure.

Consider hiring a coach if:

  • Your teen can’t keep form under load
  • They’ve had repeat injuries (ankle sprains, knee pain, shoulder pain)
  • They’re entering high school varsity training
  • You need help balancing sport + lifting + recovery

What to look for:

  • A recognized certification like CSCS (NSCA) or SCCC (CSCCa)
  • They coach movement first (warm-up, technique, progressions)
  • They can explain why they chose exercises
  • They communicate with parents and adjust for sport seasons

Red flags:

  • Max testing often
  • “No pain, no gain” culture for kids
  • Same program for every athlete, every sport

How to start this week (simple step-by-step)

Pick the schedule first

Most teens do great with:

  • 2 days/week (in-season or busy)
  • 3 days/week (off-season)

Choose 5–6 exercises per workout

Use this template:

  • 1 squat pattern
  • 1 hinge pattern
  • 1 push
  • 1 pull
  • 1 single-leg
  • 1 core

Keep the reps clean and repeat the plan for 4–6 weeks

Progress comes from repeating the basics and adding small amounts of load or reps.

Track just two things

  • Weight used
  • Reps completed with good form

That’s it.


Bottom Line: Key takeaways for strength and conditioning for teenage athletes

  • Strength and conditioning training for young athletes should build better movers first, then stronger athletes.
  • The best strength exercises for teenagers are simple: squat/hinge, push/pull, single-leg, core, plus a little jumping and sprinting.
  • Most teens need 2–3 lifting days/week to make real progress. In-season, 1–2 days/week maintains strength.
  • Don’t “out-condition” the sport. Practices and games already count.
  • If you’re unsure about form, pain, or planning, a certified strength coach is worth it.
