I hit 205lbs on a rolling thunder not long ago but today I lifted 140lbs for 20 reps. I’ve been going up and down in weight but I think for this cycle I’ll keep with the lower weight otherwise I’ll burn out too early. I need to get the blood flowing to my forearms cuz they feel permacramped
I’ve been training on the rolling thunder as well now, it’s a current model. I have to say I find it incredibly rewarding. I want to hit 205lbs though right now I have no idea what my my 1rm would be, I just pick a weight and work on form and end up doing reps I guess, I do thumbless with my left for whatever reason. I love the Ironmind Rolling Thunder!!
