Arvo vs Juggernaut AI
Methodology-driven AI training vs powerlifting-focused periodization. Compare features, pricing, and find the best app for your goals.
Juggernaut AI is the digital implementation of Chad Wesley Smith's Juggernaut Method—a periodization system that's produced world-class powerlifters. It excels at peaking strength for competition, using block periodization to systematically build toward maximal lifts. For competitive powerlifters, it's one of the most respected AI training apps available.
Arvo takes a different approach. Instead of focusing on competition peaking, it's built for continuous hypertrophy and strength development. Its 20 AI agents adapt every set in real-time, implementing five different methodologies (Kuba, Mentzer HIT, FST-7, Y3T, Mountain Dog) depending on your goals. Where Juggernaut AI plans in blocks, Arvo adapts set by set.
The price difference is significant: Arvo costs €6/month versus Juggernaut AI's $35/month. But price aside, the choice depends on your goals. Preparing for a powerlifting meet? Juggernaut AI's periodization is purpose-built. Focused on bodybuilding, powerbuilding, or continuous progress? Arvo's methodology variety and real-time adaptation offer more flexibility.

Frequently Asked Questions
Is Arvo better than Juggernaut AI?
It depends on your goals. For pure powerlifting competition prep, Juggernaut AI's specialized periodization is excellent. For hypertrophy-focused training with methodology variety (Kuba, Mentzer, FST-7), Arvo offers more options at a lower price point.
Is Arvo cheaper than Juggernaut AI?
Significantly. Arvo is free during beta and will cost €6/month post-beta. Juggernaut AI costs $35/month - nearly 6x more expensive. Arvo offers comparable AI features for strength training at a fraction of the cost.
Which app is better for powerlifting?
Juggernaut AI is purpose-built for powerlifting with block periodization and competition peaking. Arvo supports strength training through methodologies like progressive overload but is more versatile, covering both hypertrophy and strength.
Does Arvo support RPE-based training like Juggernaut AI?
Yes. Arvo fully integrates RIR (Reps in Reserve) and RPE tracking with AI-driven recommendations. The AI adapts your weights and volumes set-by-set based on your reported effort levels.
Which app has better AI?
Different approaches. Juggernaut AI uses established periodization models with weekly/block adjustments. Arvo uses 20 specialized AI agents that adapt set-by-set (under 500ms). Arvo is more reactive; Juggernaut AI is more programmatic.
Does Juggernaut AI track MEV/MAV/MRV volume?
No. Juggernaut AI uses RPE-based volume management through block periodization. Arvo tracks volume landmarks (MEV, MAV, MRV) per muscle group with automatic deload triggers when approaching maximum recoverable volume.
What's better for bodybuilding—Arvo or Juggernaut AI?
Arvo. Juggernaut AI is built for powerlifting with Squat/Bench/Deadlift focus. Arvo offers 5 hypertrophy methodologies (Kuba, Mentzer HIT, FST-7, Y3T, Mountain Dog) designed specifically for muscle growth and bodybuilding.
Can I use Juggernaut AI without a competition date?
Yes, but it's optimized for peaking toward meets. Arvo is better for continuous progress without competition deadlines—its AI adapts to your daily readiness rather than building toward a specific date.
Does Juggernaut AI have exercise videos like Arvo?
Both apps have exercise demonstrations. Arvo has 1300+ exercises with biomechanical data for intelligent substitutions. Juggernaut AI focuses on core powerlifting movements with variations.
Which app has better periodization?
Different philosophies. Juggernaut AI uses traditional block periodization (accumulation, intensification, realization). Arvo uses autoregulated periodization that adapts daily based on your actual performance data.
Is Juggernaut AI worth $35/month?
For serious competitive powerlifters preparing for meets, yes. The methodology is proven at elite levels. For general strength training or bodybuilding, Arvo at €6/month offers more versatility at a fraction of the cost.
Can I import my Juggernaut AI data to Arvo?
No direct import currently. However, Arvo's AI learns your strength levels quickly from your first few workouts. The onboarding process establishes your baseline, and the AI calibrates to your performance within 2-3 sessions.
