GPR378 User Experience
The video below demonstrates the use of the GPR378 for squats and pull-ups. It also shows someone adjusting the height setting on the power cage.
This is a heavy duty power cage for serious barbell training. You will be able to do bench presses, incline or decline presses, overhead presses, pull ups, barbell rows, deadlifts, squats and more! There are add-ons available to enable you to do dips and cable exercises.
The racks and safety pins are easy to adjust, so you will be able to switch from one exercise to another smoothly, during your workouts. You could get a full body workout with the GPR378.
The spotting racks and the J Hooks can be adjusted into 20 different positions. Each position is separated by a 3-inch increment. The J hooks can be moved to either side of the power cage, front or back.
When you get your power cage, take some time to figure out what height setting is right for each of your squatting and pressing exercises. If one setting is too high, but then the next setting down is too low, you could always put a shim under your bench or under your feet. That will help you fine-tune the settings even further.
Stability/Will it wobble or tip?
The design is very sturdy. The GPR378 weighs 225 lb when fully assembled, so it will barely move even when you are re racking heavyweights. Do you pull up a bar is also sturdy and strong. People have done pull ups on this with up to 300 lb of total weight, and it has not wobbled.
If yours has a slight wobble after you put it together, it is because everything is not aligned properly. There is a quick fix for that. Loosen all the bolts by a half turn, and then hang from all four corners of the top. That will force the rack into alignment.
In the next section, I will talk about the design of the GPR378, and explain how it can be so sturdy.
The frame is made from heavy-duty, high tensile strength steel. The 11 gauge steel features an all-four-side welded construction. The hardware supplied is oversized, and industrial strength. Each column is 3″ by 3″.
This choice of Premium materials contributes to the strength and safety of the GPR378.
To move the safety bars and J Hooks, you just push them out to the side and then pull backwards. Then you can adjust them to a higher or lower setting.
This mechanism gives you a lot of convenience, without sacrificing any weight capacity. The holes along the side fit the one inch solid steel pins, so they will not break.
The enamel paint looks great and resists chipping. The welds are clean and look professional. The simple grey and black color scheme will go well with any existing home gym equipment.
Building the GPR378 could take anywhere from 1 hour to 4 hours, depending on your skill level. Most people said it was done within 2 hours. It might help to have a friend to hold the upright beams in place as you put everything together, but it can be done alone.
The assembly mainly just involves identifying the parts based on the drawing, then threading the bolts through, and tightening the nuts. Make sure you get all the bolts through first, then go back and fully tighten them. That will ensure that everything is aligned correctly.
Nuts, Bolts, and Washers
The nuts, bolts and washers come in three numbered packages. That makes them easier to identify, and helps you build the GPR378 step-by-step.
Make sure you use the longer bolts to hold the frame together. The initial part of the instructions was said to have instructed you to use the wrong bolts. Body-Solid may have fixed this, since their user manual is available online. As soon as someone brought up the issue in the comments, Body-Solid informed their engineers. That shows their attentive customer service.
To tighten the nuts, you will just need a 19mm wrench and 19mm socket.
