Tired of not being able to get your full workout in when you’re away from home since the hotel gym only has dumbbells? The Kettle Gryp is your answer. It turns dumbbells into kettlebells. The portable adapter system reminds us of a combination of one of those extended handle bag devices and the panel mover you use for drywall or plywood, but this one is built with a durable handle and latching mechanism to clamp securely around the handle of a dumbbell and turn it into a kettlebell. The lightweight and compact Kettle Gryp is made in San Diego from tough, impact resistant ABS with urethane foam inserts and stainless hardware. Just keep in mind that you’re probably going to have to adjust your stance a little because dumbbells are wider than kettlebells. We wouldn’t want you getting overzealous and taking out your own knees.
