Step 1: Programme for a PR 📊

PRs don't happen by accident. They're the result of a well-structured training block that builds strength progressively and peaks at the right time. A basic 8-week PR programme:

  • Weeks 1–3: Volume phase — 4x6 at 70–75% of current max. Build work capacity.
  • Weeks 4–6: Intensity phase — 4x4 at 80–85%. Build strength.
  • Week 7: Peaking — 3x3 at 87–90%. Sharpen the nervous system.
  • Week 8: Deload — reduce volume by 50%. Let fatigue dissipate.
  • Week 9: PR attempt.

Step 2: Peak Properly 📈

Peaking is the process of reducing fatigue while maintaining fitness. The goal: arrive at your PR attempt with maximum strength expression and minimum accumulated fatigue.

  • Reduce volume by 40–50% in the final week
  • Maintain intensity — don't reduce the weight, reduce the sets
  • Prioritise sleep and nutrition in the final week
  • Avoid new exercises or movements in the final 2 weeks

Step 3: Get Your Equipment Right 🔧

PR day is not the day to discover your shoes are wrong. Your footwear is the foundation of your squat — get it right before PR day.

Step 4: The Perfect Warm-Up 🔥

Your warm-up for a PR attempt should be longer and more thorough than a normal session. Build up gradually:

  • Empty bar: 2 sets of 5
  • 50% of PR attempt: 1 set of 3
  • 65%: 1 set of 2
  • 75%: 1 set of 1
  • 85%: 1 set of 1
  • 92–95%: 1 set of 1 (your final warm-up)
  • Rest 5–8 minutes
  • PR attempt

Step 5: Choose Your Attempt 🎯

The most common PR failure: going too heavy. Choose a weight that is:

  • 2–5% above your current PR
  • A weight you've come close to in training
  • Not a weight you've never been near

A 2.5kg PR is still a PR. Don't let ego choose your attempt weight.


Step 6: Execute 💪

  • Take your time setting up — don't rush
  • Take a big breath before unracking
  • Walk out controlled — don't waste energy
  • Set your stance, brace hard, and descend with control
  • Drive out of the hole with everything you have
  • Don't celebrate until you've stood up completely

Step 7: Mindset 🧠

The mental side of a PR attempt is as important as the physical. Strategies that work:

  • Visualise the lift: See yourself completing it before you attempt it
  • Use a pre-lift routine: Same music, same chalk application, same setup every time
  • Aggressive intent: Approach the bar with the intention of destroying it, not surviving it
  • Trust your training: You've done the work. The PR is already earned.

Your next PR starts with the right foundation.
