Key differences.
Specialist vs all-rounder
JuggernautAI is built for squat, bench, and deadlift specialists. Strongineering supports powerlifting programs too, alongside hypertrophy, longevity, calisthenics, and hybrid training.
Recovery and mobility
Strongineering reads HRV, sleep, and resting heart rate from Apple Health and uses a movement assessment to set your warm-ups. JuggernautAI doesn't list mobility or injury features.
Cost
JuggernautAI is $349.99 a year. Strongineering is $79.99 a year, or $199.99 once for lifetime access.
