For almost any type of exercise you do, a gym mat is very important. Padding underneath your feet or body as you workout has several benefits- they help you keep your grip, provide better support for your back and can help prevent injury.
Preventing injury alone is a good enough reason to buy a gym mat for your workouts.
A full-size gym mat is sometimes called an exercise pad as well. If it reminds you of taking naps in pre-school as a child, that is because it is likely the same size, shape and material! Though some people see these as bulky, they are very good at lessening the impact of higher-impact exercises like aerobics and provide good support for your back. A good gym mat usually comes with a carrying case of some sort.
They can usually be folded or rolled into this case, making them less bulky and much easier to transport and carry.
The version you would use for yoga would be called a sticky. This is because it is made of a special material that sticks to hard surfaces. This prevents it from sliding on you when doing difficult yoga poses. This is especially important when doing a discipline like yoga because balance is required to do it correctly.
Caring for this simple piece of equipment is usually a breeze. A simple wipe-down with a damp cloth will do. Using an antibacterial wipe is even better because it kills any germs that may linger from sweat or odor after use.
A simple, ten-second wipe down after each activity will allow you to keep it in good condition for years to come.
