Most coaches make one of two mistakes in-season:
- They train too hard and fry the athlete.
- 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
1. Keep Intensity, Reduce Volume
Strength is maintained by intensity, not volume.
Instead of 5×8 back squats, do 3×3–4 at 80–85%. This keeps neural output high while limiting soreness.
2. Prioritize Lower-Body Efficiency
The best in-season lower-body choices:
- Trap bar deadlift
- Rear-foot elevated split squat
- Single-leg RDL
- Isometric mid-thigh pull
Why? They offer:
- High force
- Low technical demand
- Minimal eccentric damage
For jumping sports such as volleyball, this protects jump quality.
3. Manage the Weekly Structure
An example for one match per week:
- Monday: heavy lower body (low volume)
- Wednesday: upper body + power
- Friday: light neural activation
- Saturday: match
Two matches per week? Drop the heavy day to a micro-dose:
- 2×3 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
- Training to failure
- 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
This is where structured systems matter. In-season, consistent load and RPE tracking is one of the highest-return habits a coach can build, because availability beats 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.
