About Smith Machines
Smith Machines are the safest way for serious weight lifters to work out at home. Any experienced strength coach will tell you that working to failure is fundamental to building significant muscle mass.
A Smith Machine features a barbell on vertical fixed rails, with lock-out points up and down the track. A quick twist of the wrist engages these points, locking the barbell in place. This eliminates the need for a spotter, providing weight lifters with more independence.
Of course pushing each set to failure in an unsupervised environment can be dangerous. Smith Machines are so popular because they combine the feel of free weights with the safety of traditional resistance machines.
Smith Machines are usually a little more expensive compared to Multi-Gyms aimed at the general public.
Having a Smith Machine in your home gym allows you to perform many compound exercises safely. Compound barbell lifts are foundational to developing overall strength and muscle mass.
Why? Simply because Smith Machines are designed for experienced lifters who can move a lot of weight! That requires quality construction from a high gauge steel.
