Crimping is one of the most fundamental techniques in climbing, especially for outdoor routes with small, sharp holds. To master crimps, it's essential to develop finger-endurance, the ability to maintain strength and control over time. While campus boards are typically found in gyms, you can easily set one up at home and start training for crimp endurance.
Here's how to build your finger endurance using a campus board at home, step-by-step.
What is Finger-Endurance and Why Does It Matter?
Finger-endurance is the ability to sustain grip strength over a longer period without fatiguing or losing control. This is especially important when climbing routes that rely heavily on small holds, such as crimps, which demand not just strength but also stamina and technique. Without finger-endurance, you'll experience more pump, reduced precision, and an increased risk of injury.
Developing finger-endurance for crimps means your fingers will be able to hold onto those small holds for longer, even on routes that involve sustained crimping. Using a campus board is one of the most effective ways to train this ability.
Setting Up a Campus Board at Home
If you don't have a campus board at home yet, setting one up is simpler than you might think. You'll need:
- A Stable Frame : A sturdy wooden frame, preferably attached to a wall with a solid base for safety.
- Rungs : Purchase adjustable or fixed rungs designed for climbing. If you're using an old board or DIY project, you can use small slats of wood (make sure they're smooth and not splintered).
- Padding : Ensure the floor beneath the board is adequately padded to prevent injury from falls.
You don't need a huge campus board to get started; a small setup with a few rungs or slats will suffice for beginner to intermediate training.
Key Exercises for Finger-Endurance on a Campus Board
1. Dead Hangs for Crimps
Dead hangs are the most basic exercise and crucial for developing finger-endurance. Start with easy crimps, and as you progress, move to smaller holds.
How to Do It:
- Start by warming up your fingers with some easy, relaxed holds.
- Choose a comfortable crimp hold (larger edges for beginners, smaller for more advanced climbers).
- Hang from the crimp with both hands for 10--15 seconds, aiming for 3--5 sets.
- As you progress, increase the hang time, aiming for 20--30 seconds.
- Ensure your arms are slightly bent (not locking out) to avoid strain on your tendons.
Tip: Do not overdo it---take plenty of rest between hangs (at least 1-2 minutes). You want to build endurance, not burn out.
2. Maximal Finger Hangs
These exercises focus on building the strength required for longer crimps. This is useful when training for harder routes that demand your fingers to hold on to smaller crimps.
How to Do It:
- Choose a very small crimp or sloper (depending on your level).
- Hang from the crimp as long as possible without compromising form. Focus on maintaining tension throughout your fingers and hands.
- Record how long you can hang and try to improve the time gradually over time.
- Perform 3-4 sets, but don't push beyond your limits to avoid injury.
Tip: Rest for 3-4 minutes between each set to ensure maximum effort on the next attempt.
3. Intermittent Dead Hangs (Repeaters)
Repeaters are a great way to build sustained endurance. These involve hanging for a short period, then resting briefly, before repeating the process multiple times in a row.
How to Do It:
- Hang on a crimp for 7--10 seconds, then rest for 3--5 seconds.
- Repeat this process 5--8 times in one set.
- Complete 3--4 sets with 2-3 minutes of rest between sets.
Tip : Start with larger crimps if you're new to this and work down to smaller holds as you progress. Ensure your form stays clean, with no swinging or jerky movements.
4. Pull-Ups with Crimp Grip
Pull-ups are a great complementary exercise for building finger-endurance. Performing them with a crimp grip mimics the climbing motion and engages your finger muscles more intensely.
How to Do It:
- Use a campus board or a pull-up bar with crimpable holds.
- Perform regular pull-ups but with your fingers in a crimped position, focusing on slow, controlled movement.
- Do 3--5 sets of 3--5 pull-ups with 2 minutes of rest between each set.
Tip : If regular pull-ups are too difficult, try assisted pull-ups or use a resistive band to provide extra support until you build the necessary strength.
Training Schedule for Finger-Endurance
If you're training for finger-endurance, consistency is key. Here's a suggested weekly schedule to help you progress:
Day 1:
- Warm up with light climbing or stretching for 15--20 minutes.
- Perform 4 sets of dead hangs (10--15 seconds each), gradually increasing the duration.
- Do 3--4 sets of repeaters (7--10 seconds of hanging with 5 seconds rest).
- Finish with 2 sets of pull-ups with a crimp grip.
Day 2:
- Focus on maximal hangs (test your max finger hang time).
- Perform 3--4 sets of intermittent dead hangs (repeaters).
- Include a variety of finger grips, focusing on smaller crimps each time.
Day 3:
- Active rest day. Perform light climbing, mobility work, or core exercises to keep your body active while recovering.
Day 4:
- Repeat Day 1 workout.
Day 5:
- Focus on working through smaller crimps and longer hangs for maximal endurance.
- Test yourself with progressively smaller holds.
Day 6:
- Active rest or light climbing.
Day 7:
- Rest day to fully recover.
Final Tips
- Don't Skip Rest: Tendon injuries can happen if you train too hard without adequate recovery. Always listen to your body.
- Increase Gradually : Slowly reduce the size of the crimps and increase hang time as your finger endurance improves.
- Cross-Train : Include climbing, general fitness, and core training to enhance overall strength and stability.
- Focus on Technique : A strong crimp isn't just about brute strength---it's about efficient finger placement and body tension. Always focus on good technique.
Conclusion
Building finger-endurance for crimps using a campus board at home is a great way to develop the strength and stamina necessary for challenging climbing routes. By following these exercises and progressively pushing your limits, you'll notice improvements in your ability to hold onto small holds, manage finger fatigue, and tackle more demanding climbs. With patience and consistency, you'll be well on your way to mastering the crimp!
