Is JuggernautAI free?

No. There is a 2-week free trial, after which it is $34.99/mo or $349.99/yr. There is no permanent free tier.

Why is JuggernautAI so expensive?

Because it is priced as a coaching product rather than an app. The subscription bundles seminars, technique e-books, weekly Q&A calls with JTS coaches and a one-on-one consultation, which is a fair trade if you use them and expensive if you only want the programming.

Is JuggernautAI only for powerlifters?

Mostly. It covers powerbuilding as well as straight powerlifting, but the periodization is built around peaking the squat, bench and deadlift. General fitness, hypertrophy-only and athletic training are not what it is designed for.

Does JuggernautAI track nutrition?

No. It is training only, so you would pair it with a separate food app and do the cross-referencing between the two yourself.

Can a coach run clients on JuggernautAI?

No. It delivers the JTS system to an individual lifter and has no client roster or program hand-off for an outside coach.

How is MuscleBuddy different from JuggernautAI?

Depth versus breadth. JuggernautAI goes deeper on one powerlifting methodology than we do. MuscleBuddy gives you five progression methods to choose from, puts nutrition, recovery and bloodwork in the same loop as training, explains every adjustment, and has a free tier.

$34.99/mo or $349.99/yr after a 2-week free trial, with no permanent free tier. The price reflects a bundle that includes seminars, technique e-books, weekly Q&A calls with the coaching staff and a one-on-one consultation, so it sits closer to a coaching product than to an app subscription.

When to choose JuggernautAI

Choose JuggernautAI if you compete in powerlifting, or train as though you might. It is the productized version of Chad Wesley Smith and the Juggernaut Training Systems methodology, and the autoregulation is the real article: you report RPE and, if you record them, bar speeds, and the next session moves accordingly inside a periodized block built toward a meet date. You also get more than software. The subscription carries over 300 technique videos, weekly Q&A calls with JTS coaches, seminars, e-books and a consultation with the head coach. If your goal is a bigger total on a specific date under a proven system, and you want the methodology to make the decisions rather than configuring it yourself, this is a serious tool and the price is really the price of coaching.

When MuscleBuddy is the better fit

MuscleBuddy wins on breadth, price and transparency. JuggernautAI runs one methodology extremely well, and if JTS periodization is not how you want to train, there is no second option inside the app. MuscleBuddy ships five progression methods, double progression, RPE, linear, percentage and wave, and lets you choose which one drives each block, so the app bends to your training instead of the reverse. It is also training only: no food logging, no macros moving off your weigh-in trend, no recovery, wearable or bloodwork data feeding the decision. And the money is not close. JuggernautAI is $34.99 a month or $349.99 a year with nothing free after the trial. MuscleBuddy has a permanent free tier, and Pro is $9.99 a month with AI-powered check-in analysis and coach mode included.
