The results may surprise you. # Optimal Hangboard Training Intensity: What the Research Shows Should you train finger strength with heavy loads and short hangs, or lighter loads and longer durations? A controlled study tested different hangboard intensities to determine what works best for [developing finger strength, stamina, and endurance](/blog/10-weeks-hangboard-training-results). ## The Study Design Advanced to elite climbers (7b-8c+ lead ability) were divided into three groups training twice weekly for 4 weeks: **Group 1: Maximum Strength Focus (80% intensity)** - 80% of their maximum hang capacity - 10-second hangs - 5 sets with 3-minute rest - Added weight as needed to reach 80% **Group 2: Stamina Focus (60% intensity)** - 60% of maximum - 20-second hangs - 4 sets with 2-minute rest - Moderate intensity, longer duration **Group 3: Endurance Focus (40% intensity)** - 40% of maximum - 40-second hangs - 3 sets with 1-minute rest - Light intensity, longest duration All groups used a 23mm edge with half-crimp grip. ## What They Measured Before and after the 4-week training period, researchers tested maximum finger strength (peak force during a 5-second maximum hang), finger stamina (time to maintain 60% of max during continuous contraction), and finger endurance (time to failure using intermittent 8-2 second on-off contractions at 60%). ## Key Results **Maximum Strength Improvements** 80% intensity group improved by 12.5%, 60% intensity group improved by 9.7%, and 40% intensity group improved by 6.7%. All groups improved, but the high-intensity group showed the largest gains. The difference between 80% and 40% groups was statistically significant. **Stamina Results** No significant differences between groups. All intensities produced similar stamina improvements, ranging from 8-15% depending on the measure used. **Endurance Results** No significant differences between groups. Intermittent endurance improved similarly across all training intensities. ## What This Means **For Maximum Strength**, high-intensity training (80% of max, 10-second hangs) is most effective. This aligns with general strength training principles - to get stronger, train near your maximum. **For Stamina and Endurance**, training intensity matters less than previously thought. Both high and low intensity protocols improved these capacities. This suggests you can develop endurance during strength-focused training phases. **For Time Efficiency**, if your goal is overall finger fitness, high-intensity training may be most efficient since it improves strength the most while producing similar endurance gains. ## Training Protocol Details Here's exactly what each protocol looked like: **80% Protocol (High Intensity)** Structure: 5 sets of 10-second hangs with 3-minute rest between sets. Progression: Add weight when all sets completed successfully. Session Duration: About 20-25 minutes total. **60% Protocol (Medium Intensity)** Structure: 4 sets of 20-second hangs with 2-minute rest between sets. Progression: Add weight when all sets completed. Session Duration: About 15-20 minutes total. **40% Protocol (Low Intensity)** Structure: 3 sets of 40-second hangs with 1-minute rest between sets. Progression: Add weight when all sets completed. Session Duration: About 10-15 minutes total. ## Important Considerations **Training Experience Matters** Participants were already advanced climbers with hangboard experience. Beginners might respond differently and should start with lower intensities. **Hold Depth Was Consistent** All climbers used the same 23mm edge. Results might differ with smaller or larger edges that change the strength-endurance relationship. **Duration Was Short** Four weeks is relatively brief. Longer training periods might show different patterns, especially for endurance adaptations. **Climbing Continued** Participants maintained their normal climbing schedule. The hangboard training was supplemental, not replacement for climbing. ## Practical Recommendations **If Finger Strength Is Your Priority**, [use the 80% protocol](/programs/max-hangs-finger-strength): heavy loads, 10-second hangs, 5 sets, 3 minutes rest. Focus on progressive overload. **If Time Is Limited**, the high-intensity protocol takes less total time and improves all three qualities. It's the most efficient approach. **If Recovering From Injury**, the 40% protocol offers a lower-risk option that still improves capacity. Consult with a healthcare provider first. **For Periodization**, you can vary intensity across training phases knowing that all intensities improve stamina and endurance, but strength requires higher loads. ## Sample 4-Week Program Week 1: Test your maximum hang on your target edge. Calculate training loads for each intensity. Weeks 2-4: Train twice weekly with at least 48 hours between sessions. Week 4 End: Retest to measure progress. ## The Bottom Line High-intensity hangboard training (80% of max) produces the best strength gains while still improving stamina and endurance.
