JuggernautAI

JuggernautAI is a training app that writes individualized powerlifting and powerbuilding programs and changes them as you log workouts. It comes from the Juggernaut training brand, active since 2009, and suits lifters from beginners to competitors.

You enter your sex, age, size, strength, experience and recovery, then the system sets training volume, frequency, periodization and exercises aimed at your weak points. After each session the app uses your feedback to adjust sets, days, weeks and whole blocks.

Subscribers also get exercise technique videos, a community, weekly video Q&A with coaches and a leaderboard. A two-week free trial comes with the monthly plan, and the yearly plan adds extras such as coach consultation and seminars.
