Volume & Intensity: Complete Guide
Learn to balance volume and intensity for consistent progress and optimal recovery.
Volume and intensity are the two key variables that determine whether you build muscle, waste time, or overtrain. This guide connects all the concepts: MEV/MAV/MRV, RPE/RIR, deloads, and strength standards.
The Volume-Intensity Relationship
Volume and intensity have an inverse relationship: the heavier you go (high intensity), the fewer sets you can do (low volume). The trick is finding the sweet spot for your goals.
- Hypertrophy: Moderate-high volume, moderate intensity (RPE 7-9)
- Strength: Low-moderate volume, high intensity (RPE 8-10)
- Endurance: High volume, low intensity (RPE 5-7)

RPE/RIR Scale
| RPE | RIR | Description |
|---|---|---|
| 10 | 0 | Total failure |
| 9 | 1 | Maybe 1 more rep |
| 8 | 2 | 2 more reps possible |
| 7 | 3 | 3 more reps, solid weight |
| 6 | 4+ | Light weight/warmup |
Arvo Manages Volume & Intensity
You don't have to calculate MEV/MAV/MRV manually. Arvo tracks your weekly volume, suggests when to deload, and adjusts intensity automatically based on your response.

Frequently Asked Questions
What is MEV, MAV, and MRV in training?
MEV (Minimum Effective Volume) is the lowest volume that produces gains. MAV (Maximum Adaptive Volume) is the optimal volume for growth. MRV (Maximum Recoverable Volume) is the highest volume you can recover from. Training between MEV and MAV is ideal; exceeding MRV leads to overtraining.
What is RPE and RIR in weight training?
RPE (Rate of Perceived Exertion) measures how hard a set feels on a 1-10 scale. RIR (Reps in Reserve) indicates how many reps you could have done before failure. RPE 8 = RIR 2 (2 reps left). Both help regulate intensity without always training to failure.
When should I take a deload week?
Take a deload every 4-8 weeks depending on training intensity and recovery capacity. Signs you need a deload: decreased performance, persistent fatigue, joint pain, poor sleep, or loss of motivation. During deload, reduce volume by 40-60% while maintaining intensity.
How do I know if I'm training at the right intensity?
Use RPE/RIR to gauge intensity. Most hypertrophy sets should be RPE 7-9 (1-3 reps from failure). Consistently hitting RPE 10 leads to excessive fatigue. If you're always below RPE 6, you're not pushing hard enough. Track performance: if you're progressing, intensity is appropriate.
