Great product and great person behind it!
Just be aware that your dragonslayer may weigh a bit under or over the 20 lbs as it's just an estimate! Mine weighed pretty significantly under coming in at 13 lbs. I'm not that upset, honestly, as it's working well, and I'll be getting the adjustable weights when I'm ready for them!
Great for workouts! Forearms, back, and shoulders specifically!
