A/B Workout Rotation Schedule

An A/B rotation is a simple two-workout program: you alternate Workout A and Workout B. The challenge is that it does not always line up with a Monday–Sunday week. Re:Do’s “Every X days” scheduling is a clean fit.

Two ways to schedule A/B rotations

• Alternate every day: A/B/A/B… (useful for short skill sessions)
• Alternate with recovery days: A/rest/B/rest… (common for harder sessions)

Option 1: alternate every day (A/B/A/B)

• Create (or open) Workout A and Workout B
• Schedule Workout A as Every X days with interval 2
• Set Workout A start date to Day 1 (for example Monday)
• Schedule Workout B as Every X days with interval 2
• Set Workout B start date to Day 2 (the next day)
• (Optional) set an end date for both schedules if you want a fixed-length block

Option 2: alternate with recovery days (A/rest/B/rest)

Use a 4-day interval and offset the start dates by 2 days.

• Schedule Workout A as Every X days with interval 4
• Set Workout A start date to Day 1 (for example Monday)
• Schedule Workout B as Every X days with interval 4
• Set Workout B start date to Day 3 (two days later, for example Wednesday)

Example sequence (Option 2, starting Monday)

• Mon = A
• Wed = B
• Fri = A
• Sun = B
• Tue = A
• Thu = B

This is a rolling pattern (not tied to the week), so the weekdays shift over time while the A/B rhythm stays consistent.

Why this works

Using the same interval for both workouts, but offsetting the start dates, creates a clean alternating A/B pattern. It stays consistent even when the week boundary changes.

Common mistakes

• Wrong offsets: if the start dates are not offset, both workouts land on the same days.
• Start date off: the whole rotation shifts if you anchor on the wrong day.
• Weekly schedule instead of intervals: weekly works for fixed weekdays, intervals work for rolling cycles.

FAQ

Should I use weekly scheduling for A/B?
Use weekly scheduling if you want fixed weekdays. Use “Every X days” if you want the rotation to stay consistent even when weekdays change.
