ProArc vs. GPT

If AI is the mucle, ProArc framework is the brain.

Hybrid Intelligence

Smart Balance

Automatically balances strength vs. endurance to minimize fatigue and optimize results.

VS GENERIC AI

Guesswork Gives isolated workout ideas without knowing how today's run affects tomorrow's lift.

Built-in Safety

Injury Prevention

Hard limits on intensity and volume. We enforce recovery days so you don't burn out.

VS GENERIC AI

No Guardrails Will happily schedule dangerous, conflicting, or impossible sessions.

Real Programs

Event Ready

Complete periodised plans tailored to specific events (e.g. HYROX). Trackable workouts in the app.

VS GENERIC AI

Just Text Vague generic exercise lists that are hard to follow and impossible to track over time.

Why ProArc Delivers

Science-backed approaches that consistently outperform random training and generic programs.

Structured Programming Delivers Superior Results

Research shows that structured training plans outperform random exercise by 25-30%. ProArc's algorithm ensures your training follows proven scientific principles of progressive overload, recovery, and adaptation.

Personalization Maximizes Training Adaptations

Personalized programs improve performance by up to 40% compared to standardized approaches. ProArc's AI accounts for your specific background, goals, and constraints.

Long-term Focus Prevents Plateau and Burnout

Sustainable approaches maintain progress over 6-12 months, while high-intensity programs typically plateau after 6-8 weeks. ProArc optimizes for the entire training cycle.

Hyrox Open Doubles

“We were guessing my way through training for our first Hyrox Doubles. With ProArc, we like how it gave us clear run targets and lifts that we could recover from. If felt like we were moving the needle. We got a new double PB of 1:09 from 1:24.”

First Hyrox (8-week foundation)

“There are no Hyrox classes near me, and I didn't really know what to do to prepare. I built an 8‑week base plan with ProArc and stuck to it. Runs, strength and the stations were balanced and doable (those wall balls!). I turned up to a sim feeling ready, not wrecked.”

First Olympic Distance Triathlon

"With a full‑time job I needed a programme that made sense. ProArc organised the swim‑bike‑run build so I could tick sessions off without burning out. Achieving a top 30% finish in my age group was definitely a great surprise."
Jamie
Jamie

Hyrox breakthrough

“I’d been stuck in the high‑90s for ages. I wanted to change how I train, and took a leap of faith with ProArc. I shifted the focus to the run without binning strength, and the schedule told me exactly what to lift and when. I finally dipped under 80 at Hyrox Manchester, can't wait to see what I can do next.”

Questions & Answers

If you don’t see your question here, please email us at hello@proarc.app.

How does ProArc generate the program?

ProArc’s AI uses a tailored scientific framework to build and optimize training programs, considering factors including periodization, volume, intensity, interference, recovery and fatigue science, endurance modality, and safety protocols. The framework by default aims to adapt to user input, including current level of capabilities and goals.

How can I be confident that ProArc will work?

ProArc is designed to prioritize performance improvement over the entire training program, rather than treating each individual session as a standalone objective. Every session planned in the program is designed considering the previous training load and future sessions. The ProArc framework can adapt to multiple endurance training modalities and event-specific or general hybrid fitness targets and goals.

Can I change my program?

The ProArc app allows you to further customize your program and fully make it your own by editing the training sessions and adding/removing exercises. You could even ask ProArc AI to build you ad-hoc sessions.

Is ProArc integrated with Strava?

You can connect your Strava account with ProArc to upload your cardio activities for performance analysis against the session target, and post your strength sessions to Strava with detailed exercise details.

How do I track my performance with ProArc?

ProArc has a built-in performance logging function that allows you to record set, rep, weight, and time duration information for all your exercises. You can also check your all-time best for all the exercises you've logged.

Will ProArc give me feedback on my performance?

After uploading your cardio activity via Strava, ProArc will provide analysis based on your performance and the exercise target, providing you with execution review and future improvement points.

Is there a free version of the app?

ProArc offers free plan generation for prrogam legnth that is up to 6 weeks with a smaller LLM model.

Do you offer free trials?

Yes, all ProArc subscriptions come with 1 week of free trial. Plans can be canceled at any time and are managed by Stripe.
