In-Season Strength Training: How to Make Athletes Stronger Without Burning Them Out

Most coaches make one of two mistakes in-season:

1. They train too hard and fry the athlete.

2. They back off too much and lose strength.

Both cost performance.

The goal in-season is simple:

Maintain strength. Minimize fatigue. Maximize availability.

Let’s break down how.

The Biggest Misconception

In-season is NOT for:

• PR chasing

• High volume hypertrophy

• Constant exercise variation

It’s for performance stability.

Your athlete already has:

• Match load

• Practice load

• Travel stress

• Sleep disruption

The gym should support competition, not compete with it.

The 3 Core Principles of In-Season Programming

Keep Intensity, Reduce Volume

Strength is maintained by intensity, not volume.

Instead of:

• 5x8 back squats

Do:

• 3x3–4 at 80–85%

This keeps neural output high while limiting soreness.

Prioritize Lower Body Efficiency

Best in-season lower body choices:

• Trap Bar Deadlift

• Rear-Foot Elevated Split Squat

• Single-Leg RDL

• Isometric mid-thigh pulls

Why?

✔ High force
✔ Low technical demand
✔ Minimal eccentric damage

For volleyball (your world), this protects jump quality.

Manage Weekly Structure

Example for 1 match/week:

Monday: Heavy lower (low volume)
Wednesday: Upper + power
Friday: Light neural activation
Saturday: Match

If 2 matches/week?

Drop heavy day to micro-dose:

• 2x3 strength work

• Focus on power and freshness

What Actually Causes In-Season Fatigue?

It’s not intensity.

It’s:

• Excess eccentric volume

• Too many accessories

• Failure training

• Poor exercise selection

If your athlete can’t jump well on match day, the gym is probably too dense.

Metrics You Should Track (If You’re Serious)

• RPE per session

• Jump height (CMJ)

• Bar velocity (if available)

• Sleep quality

• Soreness index

This is where structured systems matter.

If you’re building performance software (like we are at PeakPlan), in-season load tracking is one of the highest ROI features you can build for coaches.

Because availability > everything.

The Real KPI In-Season

Not 1RM.
Not squat depth.
Not pump.

It’s performance on game day.

If your athlete:

• Feels explosive

• Recovers well

• Avoids injury

• Maintains strength

You’re winning.
