UnderForge is a personal fitness and longevity coach that builds a fully customized action plan around your body, your goals, and your life. Then guides you every step of the way and makes it easy to track progress. Whether you want to build muscle, burn body fat, increase strength, or simply get challenged by a world-class program, UnderForge forges a plan that is yours alone. CHOOSE YOUR GOAL Burn body fat Build muscle mass Increase strength Get challenged by your coach HOW IT WORKS When you join, your coach gets to know you. You'll answer a focused set of questions about your training experience, physique, schedule, nutrition, sleep, stress, and existing pain. Your coach then uses that full picture to generate a personalized hypothesis about your biggest obstacles and builds a prioritized, step-by-step action plan designed to break through them. You can review the plan and ask for revisions. This is your forge. HUMA OR AI COACH ALWAYS ON Choose between an AI-only plan and a human + AI plan. AI-only is fully complete and you have all the tools you need to achieve your goals. Human + AI plans adds a boost to accountability and even more personal touch. You decide. Ask about any step in your plan, request a technique breakdown, nutrition targets. Your coach remembers your full profile and adapts every response to your situation. Weekly check-ins keep your plan current. Progress is tracked right inside the app โ€” no need for spreadsheets or additional trackers. CONSISTENCY SCORE AS PRIORITY Most important is that you achieve consistency, therefore we created a unique score to help you stay consistent. The score is higher as you log workouts and meals. This score will also incorporate sleep and breathwork routines and adherence. TRAINING, NUTRITION AND RECOVERY SIMPLIFIED Training โ€” Personalized programming around your schedule, progressive overload, and warm-up protocols.

A real personal-trainer experience, powered by AI, in your pocket. Most apps just log what you did. dynaimic decides what you should do next โ€” adapted to your goals, your recovery, and how your last session actually felt. Two ways to train, and they work together: โ€ข AI builds today's session. Tap once for a complete workout โ€” warm-up, working sets, optional cardio and cool-down โ€” programmed around your goals, equipment, experience, training split, and which muscles have recovered. Already trained today? It asks what you're after and programs the second session around it. โ€ข Smart routines that progress themselves. Pick a template, design your own, or let AI build a full multi-week split. Then just train โ€” dynaimic auto-progresses your weights, reps and RPE week over week, and automatically deloads when a lift stalls. No spreadsheets, no guessing the next number. Running a routine but want an extra day? AI drops in a complementary session that works around the muscles you've already hit this week. WHAT MAKES DYNAIMIC DIFFERENT โ€ข It adapts session by session. Rate each workout โ€” too easy, just right, or crushed me โ€” and your training adjusts: load, volume, exercise choice and recovery dial in over time. โ€ข Smart Sessions. After a workout, your AI coach reviews how it went and proposes intelligent tweaks to your plan โ€” knowing when to push and when to back off. โ€ข Pick your coach. 29 AI coach personalities across 5 tiers, each programming and talking to you in their own voice โ€” and evolving as your bond grows. โ€ข Real progression, not random workouts. Compound lifts climb in 2.5 kg steps, isolation in 1.25 kg โ€” but only once you've earned it (sets, reps and RPE in range). โ€ข Coach reviews. Ask for a progress review and your coach turns your recent sessions, measurements and feedback into clear wins and areas to improve. โ€ข Stay hooked. Earn XP, climb the seasonal rank ladder, take on daily challenges, unlock coaches as you level up, and chase 100+ achievements. FEATURES โ€” 29 AI coach archetypes, each with a distinct style and voice โ€” AI session generation around goals, equipment, recovery and feedback โ€” Smart routines: templates, AI-designed splits, or a custom builder โ€” Automatic progressive overload with RPE targets and auto-deloads โ€” Multi-week programs, from a short block to a months-long plan โ€” Hybrid mode: AI off-day workouts alongside an active routine โ€” Exercise swaps and how-to demos โ€” Personal Records, weekly analytics, streaks and daily challenges โ€” all free โ€” Seasonal ranks, coach bonds, and 100+ achievements โ€” OLED-optimised dark mode PREMIUM Unlock the full dynaimic experience: โ€ข Up to 100 AI-generated workouts per day (free: 2/day) โ€ข Smart Sessions โ€” post-workout AI adjustments to your plan โ€ข Multi-week periodization โ€” deload and peak weeks in your programs โ€ข Unlock coaches earlier, at lower levels โ€ข Reroll your daily challenges START FREE The free tier includes full workout logging, 2 AI-generated workouts a day, analytics, streaks and challenges. Upgrade to Premium anytime; cancel in Settings.
