The Decision Tree Method

Most programs are written in advance and followed regardless of how the athlete feels that day. The Decision Tree Method flips that — the program adapts in real time based on velocity data. Every set answers a question, and the answer determines what happens next. No guessing. No wasted volume. No missed opportunities.

The 5-Step Decision Flow

1 →

Readiness Check — Warm-Up Velocity

Athlete works up to a standard load (e.g., 70% of last known max). Compare today's velocity to their baseline. Faster than baseline = green light. Slower than baseline = adjust the plan.

2 →

Load Selection — Velocity Target

Instead of prescribing a fixed weight, prescribe a velocity zone. The athlete loads the bar until they hit the target range. Some days that's 315. Some days it's 295. Both are right.

3 →

Volume Regulation — Velocity Loss Cutoff

Each set is monitored. When mean velocity drops by the prescribed percentage (e.g., 20%), the set is over. No more arbitrary rep targets — fatigue tells you when to stop.

4 →

Inter-Set Decision — Continue or Adjust

Between sets: did first-rep velocity recover to within 5% of set 1? Yes → keep going. No → drop load 5% or end the exercise. The data makes the call.

5 →

Session Review — Trend Analysis

After the session: log peak velocity, average velocity, total volume. Compare to last 4 sessions. Trending up = progressing. Trending down = recovery issue or programming pivot needed.

In-Session Decision Tree

After Every Set — Ask These Questions

First-rep velocity > target → Add 2.5-5% load. You're underloaded today. Capture the strength.

First-rep velocity in target → Perfect. Execute the prescribed velocity loss cutoff.

First-rep velocity < target → Drop 5% or reduce volume. Don't force what isn't there today.

Set-to-set velocity declining → You've passed the point of productive stimulus. Move to the next exercise.

Why This Works

No more "bad days" — the program adapts to you
No more junk volume — every rep has a purpose
Fatigue is measured, not guessed
PRs happen when the data says you're ready
Long-term progress is built on accumulated quality, not quantity
Injury risk drops when load matches daily capacity

What You Need

A velocity tracker (Vitruve, GymAware, RepOne, etc.)
A baseline load-velocity profile (3-4 sessions)
Willingness to trust the data over your ego
A coach who knows how to read the numbers
Consistency — the system improves as data accumulates

Real Example

Back Squat Session — Intermediate Athlete

Prescribed: Velocity target 0.50-0.60 m/s. Velocity loss cutoff: 20%. Sets: up to 5.

Warm-up at 225 lbs: 0.72 m/s (baseline: 0.68). → Green light. Strong day.

Working load found: 295 lbs at 0.55 m/s (normal day this would be 280).

Set 1: 6 reps before 20% velocity loss. Set 2: 5 reps. Set 3: 5 reps. Set 4: First-rep velocity dropped 8% from Set 1. → Session complete. 4 quality sets at a load 15 lbs above normal.
