'Bridge' Bodybuilding Program for the Kratos Program by Natural Hypertrophy which aims at targeting the muscular proportions of Kratos: - Huge traps/upper back - Big arms (particularly triceps) - Large and round shoulders - A thick and strong core - Less emphasis on chest and legs. This physique gives a strong and intimidating appearance, demonstrating the unrelenting power of the god of war. This program is part of Natural Hypertrophy's Kratos program. It aims at 'bridging' the novice and advanced programs by providing a dedicated arm day to decrease overall fatigue and increase arm volume. See Natural Hypertrophy's youtube video for novice and advanced variations and to understand the reasoning behind the program: https://www.youtube.com/watch?v=wB-ydKSfQ5k The program should be ran as follows: Day 1: PULL = Day 1 (e.g. Monday) Day 2: PUSH = Day 3 (e.g. Wednesday) Day 3: LEGS = Day 5 (e.g. Friday) Day 4: ARMS = Day 6 (e.g. Saturday) Some of the lifts have been modified for home gym users like myself. These are: Day 1: Platz Squat instead of Hack Squat (original) Day 1: Sit-ups instead of Decline Sit Ups AMRAP (Original) This program should be ran until progression fails/the lifter requires the true Kratos (advanced) program to keep growing.

Each session typically takes around 60 minutes to complete. That estimate covers your working sets but doesn't account for warm-up or rest between sets, so budget a little extra time when you're first learning the movements.

The program runs for 12 weeks. The structure is designed so that each week builds on the last, with weights, volume, or intensity progressively increasing as you go.
