Recommended Ab Coaster Workout Duration

For the Ab Coaster (or any knee-raise machine), a general guideline is:

• Start: 1–2 sets of 10–12 controlled repetitions.
• Progression: Add sets/reps as core strength improves; aim for 3–4 sets of 12–15 reps.
• Frequency: 3–4 non-consecutive days per week for recovery.
• Form: Avoid momentum; focus on posterior pelvic tilt and spinal flexion.

Adjust based on fitness level, goals, and any medical conditions. Consistency and proper form outweigh duration.
