Starts shipping in September Build Your Own Blob. A modular blob trainer that loads on a standard dumbbell handle. Same weight distribution as a real blob. Two halves snap together around the handle with hidden magnets, so installation takes seconds. Add weight as your grip improves, swap pieces as your training changes. Mix and match Pick your face curvatures and spacers and build what you need: symmetrical or not, narrow or wide. Replicate the feeling of a Fatman, 2nd gen York or any other popular blob. ...Or build something that doesn't have a name yet. The more pieces you have, the more combinations you get. Why train with it Other blob trainers clamp onto a loading pin. The weight hangs below the grip instead of sitting through it, and that's not what a blob feels like. Fixed-size trainers lock you into one shape. BYOB loads on a dumbbell, the balance is right, and the pieces mix and match.
