What Is %-Based Training?
Percentage-based training prescribes load relative to an athlete’s 1RM (one-rep max). For example: 5×5 at 80% of 1RM squat.
Benefits
- Clear structure: every set, rep and load is predictable.
- Great for progressions: linear, block and wave loading thrive with fixed percentages.
- Easier for beginners: athletes learn what different intensities feel like.
Limitations
- 1RM changes week to week: fatigue, stress, sleep and nutrition shift daily readiness.
- Testing issues: many athletes don’t test a true 1RM often or accurately.
- Lack of autoregulation: the load doesn’t adapt to how the athlete feels that day.
What Is RPE Training?
RPE is an autoregulated system where athletes rate how hard a set feels on a 1–10 scale. For example: 3×5 at RPE 7, meaning 3–4 reps left in the tank.
Benefits
- Adjusts to daily readiness: perfect for in-season or high-stress periods.
- More individualized: two athletes doing the same work don’t need the same load.
- Great for advanced athletes: helps manage fatigue and avoid overshooting.
Limitations
- Requires skill: athletes must learn to judge effort honestly.
- Harder to track at scale: unless your software captures RPE consistently.
- Less predictable progressions: loads may vary session to session.
So… Which System Should Coaches Use?
The real answer: use both.
When %-Based Training Works Best
- Off-season strength blocks
- Hypertrophy or volume phases
- Novice and intermediate athletes
- When athletes are well recovered and training consistently
- Powerlifting and weightlifting cycles
When RPE Works Best
- In-season training with fluctuating fatigue
- High-skill or elite athletes
- Sessions after travel, stress or tournaments
- When you want to avoid grinding reps and manage load more precisely
- Mixed training environments (team and remote athletes)
Most modern S&C coaches blend both systems: percentages for structure, RPE for autoregulation. Together they form a smarter, safer training plan.
The Problem: Tracking Both Systems Can Get Messy
If you’ve ever run an RPE-heavy program or mixed percentages across dozens of athletes, you know the headache:
- Athletes forget to write down RPE.
- Loads don’t match the intended stimulus.
- Coaches spend hours recalculating percentages.
- Progressions become inconsistent.
When you’re managing teams, remote clients or full rosters, spreadsheets and generic fitness apps fall apart quickly.
Where Modern Coaching Software Makes the Difference
A smart S&C platform should help you:
- Build blocks using either %-based or RPE targets
- Auto-calculate athlete loads
- Track RPE feedback in real time
- Compare planned vs. actual performance
- Keep training intensity consistent across the whole team
This is exactly where PeakPlan comes in.
How PeakPlan Helps You Coach Smarter (Whether You Use RPE or %-Based)
PeakPlan is designed for S&C coaches, not general fitness users. It supports both systems natively.
%-based loads that update themselves
Choose your percentages and PeakPlan calculates the load for each athlete from their latest tested or estimated 1RM.
RPE logged as athletes train
Athletes log RPE for every set, and you see it next to the intensity you prescribed, so you know whether the session matched your intent.
AI insights for each athlete
AI session summaries point out what is easy to miss in the numbers, such as an athlete who consistently overshoots their RPE targets.
Works for teams, remote clients and individuals
One platform for the entire roster.
Final Verdict
Neither RPE nor %-based training is superior. The best coaches master both, and use software that helps them apply the right method at the right time.
