The Popcorn Lift
Ideal for two reasons:
Firstly it's great when you don't have enough KB weight in one KB and need to use several to make up the weight load without the need to buy another KB; this also permits the doubling up of say a, 12kg and an 8kg KB (I'm thinking female loads here
) in order to get 20kg in each hand etc, especially if you may only own one at the higher weight of 20kg.
Secondly, it's great for grip training due to the force the handles exert, 3 handles are a lot wider than just handling one alone.
