Hey,
So in my jefferson curl sessions I work my way up to 60kg (see video). I currently weigh 71kg.
But I find that my left forearm/grip gives out before my lower back does if the set lasts a long time. Hence, I like to sort of 'burst' up from the bottom of the curl...
I'm worried that I am therefore rushing the curls (plus, there's a slight swing of the bar on each rep)... Should I lower the weight and do the curls slower or just keep hitting the 60kg until my grip strength catches up?
This isn't to say that I'm not seeing any results - I've been very satisfied with the progress I've made in my pike flexibility and overall core strength.
Any advice would be appreciated!
