you not read my post "i have ever done". it would be ignorant of me to comment otherwise. i do not see what you gain from it jumping over a bar then tapping a bag.
If u read your post it don't say that so read it back , you must of bin going at your own pace, 3 min round , 40 jumps in a min then min on the bag hard an fast round (not taping) then another 40 jumps . Do a few rounds of that then tell me it's useless , it's great for your fitness an digging deep
no doubt when you first start doing it you do have to dig deep but when you get used to it it becomes a doddle id much rather dig deep in a sparring session
Bar bag, used by countless champions over the last 25 years!! Great workout if done correctly and if you find it getting easy then try single jumps.
you dont need to jump a bar just do burpees for a minute then hit the bag hard for a minute same effect
mate maybee i was abit negative voicing my opinion but each to there own. i just do not see any gain from doing it and it does become a doddle once your fitness is back its more mind numbing than anything but if it works for you then sweet. and to answer you actual question google steel fabricators manchester and loads come i dont think its that expensive either to be honest
