Weight training tailored to you, always. Alterfit builds your program, adapts it when life changes, and tracks every set. Now on Apple Watch. Alterfit builds you a training program and adapts it to your life, whether that's an injury, missing equipment, a busier schedule, or an exercise that just doesn't feel right. We understand the frustrations of following rigid workout programs because our circumstances change often. Most fitness apps hand you a single plan and walk away. Alterfit treats your workout program as something that should adapt around your body and your lifestyle. BUILT AROUND YOU Tell us your goal, limitations, schedule, equipment, and current strength. We'll handle the rest and give you a complete, structured program in seconds - not a recycled template. ADAPTS TO REAL LIFE Tweaked your shoulder? Traveling for the weekend? Stopped progressing? Tell Alterfit and it can rework your plan around your current situation. A COACH THAT KNOWS YOUR HISTORY Ask our virtual trainer about form, a potential exercise substitution, or what to train next. It reads your actual programs, progress, and PRs before it answers as opposed to giving generic advice. For more specific requests and questions, we also have an in-house trainer who would be happy to help. LOGGING THAT GETS OUT OF THE WAY Our logging system allows you to easily track your sets, reps, effort, bodyweight, and more. For the hands-on user, we also make it effortless to structure your own workouts. From supersets, timed exercises, warmups, and even cooldowns, Alterfit aims to allow you to focus on the part that matters: the exercising. PROGRESS YOU CAN READ Track every lift, watch your PRs climb, and see your weekly training at a glance. STILL HERE? Every couple of months, Alterfit asks whether you're still seeing progress and helps you change things up if you're not. If you're not satisfied with your program, this check-in will allow you spice things up with a re-configured program catered to you. ON YOUR WRIST You may also track your workouts straight from Apple Watch. It has never been easier to log your workouts on the fly while also having metrics such as live heart rate and calories tracked automatically. Sessions save to Apple Health and count toward your activity rings. Train with a plan that pays attention. Download Alterfit and get a program built for you today.
