About john grün (marx) dumbells

[Arne]

I visited Luxembourg for two weeks ago. My goal was to examine John Grün Marx still existing equipment. Unfortunately, I didnot found his two Challenge Dumbbells weighing 65 kg and 60 kg with 70 mm thick handles. John Grün was able to clean and press this two dumbbels att the same time. Instead I found his 50 kg and 45 kg's dumbells with 70 mm rotating handles. They were both heavy and difficult to lift and I can realize how much heavier the other two dumbbells must be to lift.  

I found two blockweights of around 32,5 kg each which he put together and with one hand clean and lift over his head. It was totally impossible for me to even lift the weight from the ground. His handstrength  must have been extrem! I have sent some photos to Wannagrip.
