A bicycle, dumbbell, and treadmill are all pieces of exercise equipment. Bicycles can be used to ride around outside or even indoors, they are a great way to improve your cardio health. Dumbbells are often used at a gym but can be used at home, they help to improve muscle mass through strength training. A treadmill is a great way to improve work on your cardio health by allowing you to run inside. A book is not a piece of exercise equipment as it does not require much physical effort to engage with. A spoon will help you in eating meals, but does little to improve your cardio health or strength. A television, or TV, can be watched while exercising, but cannot be exercised with.
