136 REP BICEP CURL CHALLENGE WITHOUT STOPPING! Here's What Happened. 

Great job 👏🏼

That’s crazy! Great job!

Here are 2 best equipments for bicep curls is fat gripz and an arm blaster I've used those 2 equipments for bicep curls and they're very useful I recommend using fat gripz and an arm blaster together. You should give it a shot trust me you'll love it.

I have tried the same challenge eight months before, two hands with one single 18kg/40lbs dumbbell 270 reps in 50 minutes(both hands have 135 reps).
