Gym knobs with locks are used to secure the height, weight, or resistance of a gym machine. They are typically made of metal and have a spring-loaded pin that locks into place when the knob is turned. This prevents the knob from accidentally being moved, which can help to prevent injuries.
Gym knobs with locks are often used on machines that are used for heavy exercises, such as weight benches and squat racks. They can also be used on machines that are used for exercises where it is important to maintain a specific position, such as cable machines and rowing machines.
To use a gym knob with lock, simply turn the knob to the desired setting. Then, push the pin into the hole to lock the knob in place. To unlock the knob, simply push the pin out of the hole.
