Designed for up to four people, the Trinity XL is engineered for performance and luxury, with Finnmark’s UL-listed Spectrum Plus™ infrared heaters, a powerful Harvia KIP 4.5kW traditional sauna heater, and medical-grade Spectrum Red Light™ Therapy.

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.

Sweet Bench

The Solid Body Bench was a great addition to our home gym! Everyone uses it. Sturdy enough for the heavy lifters in our family. The leg extension add on is a game changer to our workouts. Highly recommend!

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 !!!

Favorite workout machine

I love how the Stepr fits into my space. It’s a great machine and the screen really helps to distract me from how long I’ve been on it. I highly recommended it!

Amazing!

I could not be more happy with my purchase of the Jump trainer through Select Fitness. The only regret I have is waiting so long to order it! Select Fitness customer service was top notch and I look forward to doing more business with them in the future. Thank you!

Troy VTX Vertical Kettlebell & Accessory Rack - GKBR-3
David C
Gym Quality Space Saving Storage

This is a commercial quality kettle bell rack. I needed a rack for my kettle bells in my very small space that I use as a home gym. I came across this rack on another site and it was priced much higher. Found it here at a great price and it was drop shipped from the manufacturer in about a week.
This thing is HEAVY and super stable. Absolutely perfect for what I needed!
