Hello,
I would like to pick up this topic because I don’t think that you can handle a barbell or dumbbell the way you grab a plate. And it depends not only on the available weights but space as well. If I could do the cocoons home that’s fine but in the gym I wouldn’t do.
Besides this dumbbells become very unhandy from a certain weight on, especially on twists.
Perfect would be a solution for these plate exercises where you could define the maximum available weight and the coach calculates the reps accordingly.
