The Lock Off:
Building Stronger Climbers
As a climber, your ability to hold yourself steady on a rock face often makes the difference between reaching the peak and taking a premature descent. One key exercise that can enhance your climbing is the lock off exercise, performed at various degrees of shoulder abduction. Let’s break down how to execute this exercise effectively, explore the muscles it targets, understand its relevance to climbing, and look at some alternative exercises.
1. How to Perform the Lock Off Exercise
60 Degrees of Shoulder Abduction:
Begin by gripping a pull-up bar with both hands shoulder-width apart. Pull yourself up until your elbows are bent at about 60 degrees. Hold this position. Your arms should be slightly in front of you, not directly to the sides.
90 Degrees of Shoulder Abduction:
This variation is similar to the 60 degrees lock off but requires you to pull up until your elbows form a right angle. Your forearms should be perpendicular to the ground, and your upper arms parallel to it.
120 Degrees of Shoulder Abduction:
Start just like the previous variations until your elbows are bent just slightly beyond a 90-degree angle. This position tests your endurance and strength as you maintain a wider angle.
2. Muscles Targeted in The Lock Off:
The primary muscles targeted by the lock off exercise are the latissimus dorsi, biceps brachii, and deltoids. Secondary support comes from the brachialis, brachioradialis, and the pectoral muscles. Engaging these muscles helps develop the arm, shoulder, and back strength critical for climbing.
3. Relevance for Climbers:
Lock off strength is crucial for climbers who need to hold their body in a stable position with one arm while the other moves to the next hold. This exercise improves your ability to maintain these positions longer, which is essential on overhangs or when negotiating holds that are far apart. The different angles allow you to train your muscles to adapt to various ranges of motion, mimicking the different reaches you might need during a climb.
4. Alternative Exercises to a Lock Off
If you’re looking to diversify your training, consider incorporating these alternative exercises:
Frenchies:
Perform a pull-up and hold your chin over the bar for a few seconds. Lower to the mid-point and hold, then lower to just above full hang and hold. This variation increases endurance and strength through the full range of the pull-up motion.
Isometric Bicep Holds:
Using a weight that is challenging but manageable, hold a dumbbell at different angles (similar to the lock off angles) to strengthen the biceps and forearms.
Dead Hangs:
Simply hanging from a pull-up bar will build grip strength and shoulder stability. You can vary your grip width and type (e.g., using a towel or different grips on a hangboard) to further challenge your muscles.
Conclusion:
Incorporating the lock off exercise into your training regimen will not only boost your upper body strength but also enhance your ability to tackle difficult climbs with confidence. Mix these exercises into your routine to keep your workouts fresh and your muscles always guessing. Happy climbing!
