Cassette Manual
The Cassette is a versatile grip training tool and features multiple exercises, adjustments and resistance options. It is a comprehensive training solution that fits right in your pocket. Take a look at the Owner's Guide to get the most out of your Cassette.
Choosing the Right Training Intensity (Determining MSL)
To get the most out of your training, and to quantify progress, it is very important to determine the maximum load you can control with good technique. That value is called MSL and is the foundation of OGC training protocols.
Grip Maintenance & Injury Resilience Protocol
Hard climbing places extremely high loads on the fingers, wrists and forearms. By training at 50 - 70% of your maximum capability, you stimulate the muscles and tendons enough to maintain strength while promoting tissue adaptation with minimal fatigue. This protocol emphasizes quality movement, controlled repetitions, and consistent volume rather than heavy loads. It covers every major grip type as well as wrist and forearm conditioning, recommendations for progression and points regarding safety.
Grip Recovery & Rehabilitation Protocol
Recovering from a climbing injury requires patience and consistency. Unlike strength training, rehabilitation focuses on restoring tissue capacity. Gradually increasing load encourages collagen remodeling, improves circulation, restores movement quality, and helps tissues regain the ability to tolerate climbing-specific forces. This protocol is intended as a general guide and reference for progressive rehabilitation.
Grip Strength Development Protocol
Strong fingers are one of the greatest predictors of climbing performance. Unlike maintenance training, which emphasizes tissue resilience, strength development intentionally overloads the muscles and tendons to stimulate adaptation. This Protocol teaches you how to find your Maximum Sustainable Load (MSL) and how to use it as a metric to determine appropriate load for your exercises.
