Great way to warm up before lifting or to wear during exercise. There are so many different ways to use them, and you can always watch MB videos to learn how.
What can you say about horse stall mats? They do the job and keep the floor protected. I recommend power washing them and scrubbing with Dawn dish soap before bringing them inside to clean and reduce the smell. They do need to air out.
Anytime I use my SSB bar or speciality bars, you'll find these collars holding the plates in place. Highly recommend if you don't want plates moving around or slipping off the collars.
I have all the MB Slingshots, but this is my goto slingshot. I find the way the angle is sewn in to the slingshot very helpful. I really enjoy all the MB products and find them helpful in reducing any shoulder pain.
