The 75% Rule: How to Train Smarter and Get Better Results

If you’ve ever felt burnt out after a brutal workout, you’ve probably been missing a simple trick – the 75% rule. It’s not a myth; athletes from the gym to the rugby field use it to push hard enough for gains while keeping fatigue in check.

So what is the 75% rule? In plain terms, it means you work at about three‑quarters of your maximum effort. Whether you’re lifting, running, or practicing a skill, you aim for 75% of the weight you could lift once, 75% of your top sprint speed, or 75% of the intensity you could sustain for a single rep.

Why 75% Works Better Than All‑Out Effort

Training at 100% feels impressive, but it also spikes injury risk and prolongs recovery. At 75%, your muscles get enough stimulus to grow, your heart improves its efficiency, and you avoid the burnout that comes from constantly maxing out. Think of it like driving a car – you don’t need to floor it to reach your destination; a steady 75% throttle gets you there faster and safer.

Research in strength training shows that sets done at 70‑80% of one‑rep max (1RM) produce the most muscle hypertrophy. In endurance sports, working at 75% of VO2 max boosts aerobic capacity while keeping the training load manageable. The rule also fits well with periodisation – you can cycle harder weeks with lighter ones without overtraining.

Practical Ways to Use the 75% Rule in Your Routine

Gym lifts: Find your 1RM for a bench press, squat or deadlift. Then load the bar to roughly 70‑80% of that weight. Perform 3‑4 sets of 8‑12 reps. You’ll feel the burn but still leave a few reps in the tank for the next set.

Running or cycling: Use a heart‑rate monitor or smartwatch. Aim for 75% of your max heart rate (usually around 140‑150 bpm for most people). This feels like a comfortable hard pace where you can talk in short sentences.

Team sports drills: When practising rugby tackles or basketball sprints, ask players to execute at 75% effort. They’ll retain technique and speed without the fatigue that drags performance down later in the game.

Schedule: Start each week with two 75% sessions, one high‑intensity (90% for a short burst) and one low‑intensity (60% for recovery). This mix lets you reap the benefits of both intensity and volume.

Remember to track progress. Write down the weight, speed, or heart‑rate you used, and note how you felt. After a few weeks you’ll see lifts getting heavier, runs feeling easier, and recovery times shrinking.

Finally, listen to your body. If a 75% effort still feels too hard on a particular day, dial back a few % – the rule is a guideline, not a law. Consistency beats occasional overkill every time.

Give the 75% rule a try in your next workout or practice. It’s a small adjustment that can lead to bigger, steadier gains without the crash‑and‑burn of constant maxing out.
