No matter the style or brand, weight benches come in two varieties: adjustable and non-adjustable. Adjustable benches let you change the angle of the bench to suit your workout goals. Non-adjustable benches have one fixed angle.
With adjustable weight benches, you can do incline presses, flat presses, decline presses and more. You can also easily adjust the bench for different exercises. For example, a decline bench lets you work your chest muscles by doing decline flies or other exercises on the bench.
Non-adjustable weight benches are less expensive than adjustable ones. However, they don’t provide as many options for working out your chest, shoulders and triceps muscles. And since their angle is fixed, you can’t lower them for triceps, dips, or other exercises that require a low bench position.
