GymACE is your personal gym buddy:
• Huge exercise database, gym and body weight, with descriptions and images.
• Detailed workout planning with supersets, alternative and optional exercises
• Customize workouts, exercises and categories, turn off the integrated database, and/or link your own exercises to integrated exercises.
• You can do each exercise one after another, but you can also skip exercises, do them in a different order, or do extra ones. You can also do as many sets as you want, or as the situation in the gym requires. GymACE does not restrict you in any way.
• Suggests weight and reps based on previous sets and sessions.
• Has three countdown timers to monitor your rest periods. They can be set to start automatically when you enter a set or switch to the next exercise.
• You view your results in a concise, compact format grouped by session date and exercise. With the Calendar view you can view an entire month of workouts at a glance.
• Shows your previous workout results right on the input screen, so you know what your goal is - no searching, no tabbing, it's just there.
• Calculates your One Rep Max (1RM) for each set and tracks your all-time best, which it celebrates with a user selectable sound effect.
• Track your records
• Draws a graph of your One Rep Max, repetition, volume or weight history for each exercise.
• Detailed fitness and body statistics with predefined and custom data fields
• Smart handling of body-weight routines (count reps) vs. weight routines (calculate One Rep Max).
