Custom fit each machine.
Some machines require a single adjustment, such as the seat height, while others require two or more adjustments: Usually in these cases you just pull a pin out of the hole, lower or raise the seat, and then put the pin back in place. Some machines are so simple to adjust that they don’t even involve a pin. With practice, fitting the machine to your body becomes an usual and simple task. However, you should remember that using a weight machine that doesn’t fit your body is uncomfortable or even dangerous. When you strain to reach a handle or sit with your knees digging into your chest, you’re at great risk to pull a muscle or wrench a joint. After you make an adjustment, jiggle the seat or the backrest to make sure that you’ve locked it securely in place.Watch your fingers.
Sometimes a machine’s weight stack gets stuck in midair. Don’t try to rectify the situation yourself by fiddling with the plates. Instead you should call a staff member for assistance. There were cases when gym
member try to fix a weight stack himself. The stack came crashing down, sandwiching his fingers between the weight plates.
Buckle up. If a machine has a seat belt you are required to use it. The seat belt prevents you from wasting muscle power squirming around to stay in place as you move the bar or lever of the machine. You’re most likely to find seat belts on older models of the inner/outer thigh, pullover, seated leg curl, and triceps dip machines.
Don’t try to invent new uses for the machinery. You wouldn’t use your favorite t-shirt to dust the house, right? You wouldn’t use your monitor as a step-stool to reach the top cupboard. So don’t use a chest machine to strengthen your legs or other parts of your body.
