I just bought a 50# kb this evening from wallys.
I wanted a 16kg(35lb) to match my other 16kg. But they had none I saw.
No time to visit other stores soo.
They had a 30lb and a 40 and a 50.
I did a one hand swing and into a shoulder rest and then a press with 50.
It felt so good. Very controlled and I felt the muscle chain firing.
I trained with my 16kg for over a year.
I also have a 85lb kb I got a couple years ago but only used w two hands a few tines.
