Fire Your Trainer

Kiwi is an AI personal trainer app for iPhone and Android. It builds your strength-training plan around your goals, schedule and equipment, adjusts it as you log workouts, and answers your questions in chat any time.

Most personal trainers are expensive, inconvenient, and generic. Kiwi Fitness delivers personalized, gym-ready strength workouts with video support, tracking, and adaptive AI — at a fraction of the cost. No rescheduling. No awkward small talk. No $100/hr price tag. Just progress.

Today's workout in the Kiwi app: 45 minutes for muscle gain at an intermediate level, adjusted for back pain

Logging an overhead press in the Kiwi app: 4 sets of 15 reps at 75 lb

Activity stats in the Kiwi app: streaks, 123 logged activities, top 16% for age and gender, and a list of logged workouts

Is Kiwi or a personal trainer better for me?

It depends on what you need. If you want a plan built around your goals and schedule that adjusts after every workout, with answers whenever you ask, Kiwi does that for a fraction of a trainer's cost. If you're new to lifting and want someone checking your form in person, or you're coming back from an injury, a trainer or physical therapist is the better choice, and Kiwi works well between sessions.

As of October 2026: free to download on iPhone and Android, with a free week before the subscription starts.
