Try This Move: Iso Kettlebell Curls
A fun way to add some diversity to your curls
Isometric Kettlebell Curls
I didn't have matching weights so I used a 15 lbs for the hold and 26 lbs for the concentric movement. I also had my Ruck Pack on with a 30 lb plate in it.
Tuck your tail bone, squeeze your glutes and engage your core as you curl the kettlebells towards you. When the isometric arm (15 lb in my case) reaches 90 degrees hold it there, continuing to curl with your other arm for 10 reps.
Keep your gaze straight, at a neutral angle. Keep your chin tucked.
Switch the weights and repeat on the opposite side.
3 sets x 10 reps per arm
