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.

A real personal-trainer experience in your pocket. Most apps just log what you did. dynaimic plans what you should do next, around your goals, your recovery and how your last session actually felt. TWO WAYS TO TRAIN โ€ข Your coach builds today's session (Pro). Tap once for a complete workout (warm-up, working sets, optional cardio and cool-down) planned around your goals, equipment, experience, split and which muscles have recovered. โ€ข Pick a plan and follow it. Choose from 55+ plans with picks for you, build your own routine, or have your coach build a program that changes block by block. "Up now" always shows the day you're on, ready in one tap. Training off a plan someone else wrote? With Pro, paste it in and it becomes a routine: days, sets, reps and rest. STACK: TRACK YOUR SUPPLEMENTS Your supplements, one tap per dose. Creatine, protein, vitamins, electrolytes, 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. Everything you log stays yours. It never turns up in a coach message or a leaderboard. dynaimic records what you enter; it doesn't dose or advise. WHAT MAKES DYNAIMIC DIFFERENT โ€ข It listens after every session.
