FitnessOne

FitnessOne is the first iPhone app that can create a custom, day-by-day workout plan that guides you through gym or home workouts for up to six months. Every FitnessOne workout (there are over 70) is created by a professional, certified trainer, and each trainer is certified by the NSCA, ACSM and NASM, so you can be sure you’re getting effective and proven recommendations.
