PowerBlock 2.5 - 50 lbs dumbbells
Carrying them down the stairs wasn't quite so happy, but still good. I also got 2 - 25lb plates for my barbell and some spring collars. And a very rubber smelling mat for the floor. I only mention the smell because I realised on my way home there was a funny rubber smell in the vehicle. I know it will go away a little.
I'd maxed out the dumbbells I have the other day. I'd been using some odd combinations (water filled weights I had for travel / sand filled weights / wrist weights), but 20 lbs was the real max in the end. So when I hit that yesterday in the shoulder press (and getting close on the lunges) I decided it was time. The plates for the barbell could have waited maybe a couple of weeks, but since I was there I figured I might as well.
I picked the PowerBlocks because I can add on to them if I ever need to. I wasn't sure if 50lb ea would be a max or not.
