Bicep kettle bell curl/ straight bar

Do this superset as written below.

1) Heavy straight bar curl: 6-8 reps

2) Light kettle bell concentration curl:
   Notice I’m fully bent over and grabbing the kettle bell by the handle (only 12.5 pounds) doing 8-10 curls, focusing on flexing my bicep as hard as I can on each rep. Keep the wrist straight when holding the kettle bell by the handle. Very important!
