Our team caught SAN Athlete and fitness model Diego Sebastian in the middle of an intense arms & abs workout at Olympia 2015.
We asked if he'd share his routine for an intense biceps, triceps, and abs workout.
Diego trains with functional supersets that begin with a primary lift at 80% max weight. He then immediately supersets a second lift for the same muscle group but cuts the weight in half. This intensity technique gives him maximum growth in minimal time.
