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. Tailored to gym, home, or park training and available equipment. Nutrition โ€” Macro and calorie targets and guidelines based on your goals and body composition and preferences.

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 โ€ข Your coach 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, split, and which muscles have recovered. โ€ข Routines that progress themselves. Pick a template, build your own, or ask for a multi-week program that actually changes: each block gets its own split and its own exercises, instead of repeating one week forever. dynaimic climbs your weights, reps and RPE week over week, and deloads when a lift stalls. Training off a plan someone else wrote? Paste it in and it becomes a routine โ€” days, sets, reps and rest. NEW: STACK โ€” TRACK YOUR SUPPLEMENTS Your supplements, one tap per dose. Creatine, protein, vitamins, electrolytes โ€” grouped by when you take them, with a streak and a 12-week consistency grid for each one. Search the library or add anything you track yourself: name it, set the dose and the schedule, and get reminded only on the days that item is due. Everything you log stays yours. It never turns up in a coach message, a leaderboard or a notification. dynaimic records what you enter โ€” it doesn't dose or advise. Free for everyone. 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 load, volume, exercise choice and recovery dial in over time. โ€ข Pick your coach. 29 AI coach personalities across 5 tiers, each programming and talking to you in their own voice. โ€ข Real progression. Compound lifts climb in 2.5 kg steps, isolation in 1.25 kg โ€” once you have earned it. โ€ข Honest numbers. Band exercises record the band you used instead of a made-up weight, and rest timers follow the rest your program prescribes. โ€ข Stay hooked. Earn XP, climb the seasonal ranks, take on daily challenges, and chase 100+ achievements. FEATURES โ€” Stack: log supplements, protein and vitamins with reminders and streaks โ€” AI sessions built around goals, equipment, recovery and your feedback โ€” Routines: templates, AI-designed multi-week programs, or your own builder โ€” Import a written program and turn it into a routine โ€” Automatic progressive overload with RPE targets and auto-deloads โ€” Exercise swaps ranked by useful difference, for your gear or a full gym โ€” 1,000+ exercises with how-to demos โ€” Personal Records, session summaries, analytics, streaks and challenges PRO Coach-written workouts, multi-week programs and training reviews are Pro, along with plateau detection, optimal starting weights and the premium coaches. FREE Stack, template and custom routines, full logging, history and analytics, exercise swaps, challenges, streaks and coach chat โ€” free, with no trial to cancel.
