Standard/go to attachment and cable accessory. This has been used for cable exercises in a personal gym for over 15 years with no issues or maintenance needed.
Cheaper collars found on Amazon and other sources. I've used these for regular lifts for years with nothing negative noted. Ended up getting three pairs to have plenty for the gym.
One of the smaller companies that produced bags for a while. It is indeed a no frills bag, but gets the job done. Feel is a little looser tan some of the bigger companies.
While these were a good idea and easy to make for someone who can do concrete work, they can be a bit unwieldy and the edges can draw blood. When I first made these, I couldn't even get them off the ground.
My first loading platforms was a row of 4x4s in the rack. The leftovers went to this by simply racking a few pieces of 4x4 together. I also have other single pieces of 4x4 I place under to.elevate each one when needed.
The basic dumbbells where it started. They hold up well as long as they aren't clanging and banging together (a previous set I was using for chest flies chipped away due to this)
