My trainer is obsessed with doing drills with one person having their foot in a tire. This person jabs while the person outside of the tire slips and counters. He says that the tire is important to keep that person from "running away" from the counter. I always though that the point of the tire was for both people to have their feet inside - to keep them close. I think it feels very awkward and unnatural to be jabbing at someone while your foot is stuck in a car tire, and then having the defend counters while your foot is stuck and you can't move or balance properly. I can't step with the jab. I can't use footwork. It's starting to give me bad back strain. I mentioned this to the trainer and he said "you must use it, it stops you from running around". Has anyone ever heard of this method. Seems bogus to me and I think I'm going to change gyms.
