GPR378 Power rack

The power rack included in this package is the Body-Solid GPR378 model. The frame of this rack is of 11-gauge high tensile strength, 2″ x 3″ (5.1  x 7.6 cm) steel tubing. All its steel parts have an electrostatically applied powder coat finish, highly resistant to rust and scratches. The colors used are silver for the frame bars, black for the safety bars, J-hooks, and a pull-up bar.

The heavy rack, weighing more than 220 lbs, offers excellent stability. So it’s unnecessary to anchor it to the floor, and its bases don’t have holes for that purpose. But if you want it attached to the floor, it’s possible to drill holes in its plates. This will void the warranty, though. Placing it on a rubberized mat will also add stability.

The rack’s footprint is not extremely large. Although it’s advertised as a light commercial power rack, it’s best suited for home use. Commercial power racks are usually much broader and taller. Anyway, the rack’s footprint takes 49″L x 46″W (124.4 x 117 cm) of floor space.

Body-Solid GPR378P300 Power Rack Package

And considering that the upright steel tubes are 3″ x 3″, the width inside the cage is approx — 40″ (101.6 cm), offering enough space even for heavier users. However, don’t forget that the overall width of the set includes the 7′ Olympic bar. Therefore you will need an area more extensive than 7′ lin to use this rack correctly and safely.

Regarding height, the top of the frame is 80″ (203 cm) above floor level. This means it can fit in a room with a 7′ ceiling, but it would be pretty tight. Also, in a room with a 7′ ceiling, the clearance above the frame will be only 4″ (10 cm), which may not be enough to execute various chin-ups or pull-ups properly.

Safety bars, J-hooks, and a pull-up bar

The Body-Solid GPR378P300 includes a set of two safety bars and two J-hooks. The recommended weight is 800 lbs (362.8 kg), although users have reported that it can hold up to 1,000 pounds (453.5 kg). Also, the frame features 20 adjustment positions for them.

The pull-up bar is attached to the top front of the frame. It measures 41″ (104 cm), it’s 1.5″ (3.8 cm) thick, with knurled grips. It does not have a rubber foam coating on it. Also, this bar should support more than 400 lbs (181.4 kg) of user weight. In other words, it can withstand weighted pull-up exercises without any issues.

GPR378 included Bench

This Body-Solid weight training set contains the GFID71 bench. This is a heavy-duty flat/incline/ decline bench with a weight capacity of 1,000 lbs (453.5 kg). Its frame is made of the same 11-gauge steel tubing just as the power rack; however, the tubes are 2″ x 3″ (5 x 7.6 cm).

The upholstery on the bench is highly durable, made of 2¾” (7.2 cm) DuraFirm padding, offering all the comfort required for your workouts.

The Body-Solid GFID71 bench has a footprint of 70″L x 28″W (178 x 71 cm) and an assembled weight of approx. 101 lbs (45.8 kg).

The backrest features six adjustment positions. It can go to an almost 90° setting for incline workouts while for a decline for 30°. It also has a flat (0°) setting. When the backrest is at 0° incline (flat), the floor’s distance to the bench pad’s top is approximately — 20″ (51 cm).

The seat is also adjustable, featuring several adjustment positions. For example, it tilts from its normal 0° position to support specific exercises. The seat pad’s dimensions are 12″ x 10″ (30.4 x 25.4 cm), while the backrest dimensions are 35.5″ x 10″ (90 x 25.4 cm).

The front part of the bench is equipped with a T-Bar Leg to Hold Down accessory with oversized rollers for extra comfort and stability. However, this part is removable and is replaceable with a leg developer or a preacher curl pad.

GPR378 includes a Weight set

The included weight set for this weight training system is the Body-Solid OSB300S. This set consists of a 45 lb 7′ Olympic barbell and the following Olympic-type weight plates:

  • 2 x 45 lbs (20.4 kg), 2 x 35 lbs (15.8 kg), 2 x 25 lbs (11.3 kg), 2 x 10 lbs (4.5 kg), 4 x 5 lbs (2.26 kg), and 2 x 2.5 lbs (1.13 kg)

The total weight of this weight set is 300 lbs (136 kg).

The weight plates are solid cast iron with a paint finish. However, they don’t feature any rubber coating or vinyl. Instead, the barbell has a chrome finish with knurled grips to provide superior adherence. The weight set also includes two EZ collar springs to hold the plates safely on the bar.

This Power Rack Package is available with a 500-pound weight set for the more accomplished powerlifter. For pricing, I’ve provided this link Body-Solid GPR378 Power Rack with Heavy GFID71 Bench, 500lb. Weight Set

GPR378 Assembly and Maintenance

The Body-Solid GPR378P300 power rack and the GFID71 bench are relatively easy to put together. Also, each one comes with its assembly manual. However, due to the many parts required to be attached, the whole assembly process may take a few hours.

Maintenance requires periodic checks of the rack’s and bench’s bolts and joints to ensure they still hold tight in place. Moreover, this is to prevent any potential accidents or failures of the equipment.

  1. This sturdy frame that can hold up to 800 pounds seems like a great choice for most home gym weight training setups. Although, I could see where not having storage pegs for weight plates might be a deal-breaker for some people, as that can be a very handy feature to keep plates close for easy weight adjustments. Thanks for the in-depth review of this piece of equipment!

  2. Considering the number of exercises possible, that alone is making me consider buying this solid gpr378 gfid71 300lb weight set. To be honest, it seems like a giveaway price considering what it offers and how sturdy and firm it is. I truly fancy this post a lot and I must surely suggest this to my hubby. Since we are building our home gym, this would be a great addition. Thumbs up

  3. A power rack, a good bench, and weights. Wow, this is really a whole lot packed into the package! Seeing all the features of this is really good. A 300lb weight set is not so bad I must say. Is it possible to get storage for them separately since it doesn’t come with one on its own?

  4. Now this matches what i have been searching for. I am in process of setting up a fitness centre and i have been looking for the right equipments to get for it. So far some of the equipments i have come across doesn’t doesn’t really suite what i need it for or are either of less quality, and I can’t settle for less. Looking at the numerous benefits of this work out equipment, I’ll love to get it for my gym centre. Thanks for the information.

  5. You have really done the research on this product in great detail.  It sounds to be constructed very well with heavy duty steel and has the weight that will keep it steady.  With the bench, weights, pull up bar, j hooks and safety bars I can’t think of anything else I would need for a great work out.  I’ll be seriously considering this product.  Thanks for the detailed review.
