Isometric holds are a forgotten strength-building technique that involves contracting muscles without changing their length, creating tension while holding a static position. This method triggers high-threshold motor unit recruitment and helps develop real-world strength that translates to everyday movements. Isometric holds force the body to stabilize itself in space, making them more functional than machine-based training.

Isometric contractions build strength differently than dynamic movements by generating maximum tension without shortening or lengthening the muscles. Essential isometric holds include the wall sit, hollow body hold, doorway chest hold, Bulgarian split squat hold, and horse stance. Implementing isometrics can improve joint health, functional strength, and help break through training plateaus.

To incorporate isometrics effectively, start with 20-30 second holds and progress to 60+ seconds, focusing on perfect position and maximum tension. Isometric training can be integrated with dynamic training for complete development and is used by elite athletes to break through plateaus. A 30-day isometric challenge involving the forgotten five holds can help develop foundational strength that supports all fitness goals without the need for fancy equipment.
