This set up is perfect for my home gym!

Fringe Sport Savage Bumper Plate Sets
LedHed
Got them for a great price.

Service was prompt and helpful. Bumpers delivered in perfect condition. Zero complaints.
25 and 45LB bumpers were spot on for weight, 10LB fell short of the advertised accuracy at 9.4LB, should be +/- 1% or 9.9LB, but when I weighed the full stack it came out to 159.8lb so it might just be my scale at lower weights. The widths were important to me because I use a shorty bar with 9" sleeves, these are pretty narrow for bumpers. The weights & widths can be seen in the pictures. I'm not really into gym equipment aesthetics, but I do find the colored plates nice for quick identification. There was no rubber smell. They were packaged well, note that there are two 25LB plates in a box. Overall the experience with SelectFitness was great. I'm happy with the purchase.

Great Dumbbell Rack

I just got this triple tier dumbbell rack with saddles for my home gym. It comfortably fits 15 pair of round dumbbells. It was reasonably priced, easy to assemble and is very solid. I
love it and highly recommend it.

Body Solid Power Rack With Cable System

I bought this rack and system about a month ago. It took about a week to arrive which is pretty great considering how big and logistically difficult the order/product is.

I put it together myself, so it is the possible. However having a second set of hands would have been nice.

Once this bad boy was put together I’ve been wearing it out. I don’t have it bolted to the floor but there is no wobble when racking weights. The pulleys are very smooth. I was a little worried about that based on a lot of videos that I watched saying how aluminum pulleys are superior. I can’t imagine how they could be. The pulleys on this are great.

I have used it all but two days since I’ve had it. No complaints at all.

Great option for low ceiling spaces.

Body Kore standing chest supported t-bar row

I searched and searched for a chest supported t-bar row.. I knew I wanted something commercial grade as I've been upgrading my home gym with better equipment. There are lots to choose from, all ranging in price from high to low.. I am so happy I landed on Select Fitness website and chose this piece. Right from the get go the communication from customer service was on point and the shipping was quite fast as well.. When my equipment arrived I got it inside, downstairs to my gym, unbound and assembled by myself in about an hour and 45 minutes and I took little breaks to. This piece is so solid and well made!! I am able to take my back workouts to a whole new level that feels great and I can't wait to grow.. Take my word for it and look over Select Fitness website for any of your gym needs and happy lifting !!!
