Here’s another intense 6-12-25 Bicep Workout with MB.

We like to use 6-12-25 at the end of a session in order to get enough volume on a remaining body part, for sessions that have a restricted time length, and to add variety to our training. To perform 6-12-25 workouts it is recommended to go by the following instructions and then complete the 6-12-25 sets 3-5 times with a 120 second rest between each:

  • 6 reps of a compound exercise, with a 4 second eccentric phase and explosive concentric phase.
  • 12 reps of a slightly less taxing compound exercise, with a 3 second eccentric portion.
  • 25 reps of an isolation (works through one joint) exercise, with a 1-2 second eccentric.
