Today Hany Rambod the "Pro Creator" and coach to 15 Olympia titles and counting as of 2015 is featuring approximately 70 seconds on FST-7 tips for overhead dumbbell Extension.
Hany uses this as a foundation exercise. Typically it will be the 2nd or 3rd movement after the triceps are warmed up. Use moderate weight avoiding any swinging or use of momentum. Use a full range of motion without locking out the elbows. Hany will stop his athletes short of lockout to keep full tension on the muscle throughout the entire movement. If you have a spotter finish with partials for added intensity.
