What is a Smith Machine? 

Similar to a squat rack or power cage, the smith machine can be used to perform all the main powerlifting moves, but unlike the other two, the smith machine has some moving parts in it.

The barbell on the smith machine is connected to an attachment which is installed on the vertical guide bar. The barbell is an integrated part of the machine. The barbell can be rotated a little to engage or disengage the hooks installed on it with the pins on the rack upright.

The barbell can slide smoothly along the guide bar or rail in a vertical direction. There are pins at various positions on the frame upright so that you can rack the barbell at any height by just twisting the barbell a little.

Almost all smith machines have a shock-absorbing mechanical spotter at the base to catch the weight in case you are not able to twist the barbell to lock it in a position.

Smith machine has several weight posts on the frame. There is provision for different attachments like cable pulley or benches.

What is a Squat Rack?

Squat racks are the gym machines that specifically help you perform squats with free weights more effectively and safely. These are usually solid, single-piece structures put together by welding or bolting the heavy-duty steel tubes.

The two uprights at the back of the structure are straight and have Olympic size or regular weight posts on them. The uprights in the middle are angled to meet the back uprights at the top. This angle also helps you rack and unrack easily while squatting.

The middle uprights have several equidistant hooks to accommodate the Olympic size barbell at different heights. The uprights in the front are there to support the spotter arm. Usually, a single steel tube is bent and welded at the base and to the middle upright to form the upright and spotter arm.

The top of the spotter arms and the hooks on the upright are lined with hardened rubber or similar material to make the racking noise-free and to protect the barbell from scratches.

Working out using free weights like barbells and dumbbells is rewarding but it poses a risk of injury and there is always a chance of failed rep if you are working with heavier weights. If you are one of those who like to work out with a heavily loaded barbell at your basement gym then you do need to have a squat rack to support you in this endeavor.

If it is not feasible for you to bring a spotting partner with you for every workout session then even if you are exercising with moderate or light weights, you should have a squat rack.

What is a Power Rack?

A steel cage where you workout inside the limits of four vertical sections of the gym machine is a power rack. The power rack is often called a power cage as the structure with four uprights encasing you in while lifting looks like a cage.

The four vertical members are 2×2 or 3×3 inches heavy-duty steel tubes installed on a solid base. These uprights have equidistant holes on it for installing the J-hooks and spotter arms at different heights for different exercises.

The barbell can be placed on J-hooks installed on the uprights at the back. The spotter arms cover the whole depth of the structure and have one end installed on the front and the other on the back upright. As you will be working out inside the cage, there is no chance of the barbell falling outside the range of the spotter arms.

What’s The Difference Between Smith Machine And Squat Rack?

The basic difference between a smith machine and a squat rack is the smith machine can be called a complete gym machine in itself and the squat rack is a platform that together with other gym equipment can be used to perform different exercises.

The smith machine has moving parts in it as the barbell is a part of the machine that slides along the guide bar and can be rotated inside the bearing. The squat rack is a stationary structure for supporting the free weights.

You can move in a restricted straight line pattern while using the smith machine.
