Pamela Reif’s ab workouts have accumulated hundreds of millions of views for a reason: they’re well-structured, genuinely difficult, and efficient. This 10-minute routine is one of her more demanding entries — it’s titled “killer” and it earns it. The pacing is unforgiving, the exercise selection is varied, and the total time investment is minimal.
What Makes This Routine Effective
The variety of movements in a 10-minute window means the abs are hit from multiple angles and through multiple movement patterns — flexion, rotation, anti-rotation, and isometric holds. That comprehensive stimulus is more effective for core development than running the same 3 exercises for the same rep counts every session.
Reif also keeps rest minimal, which creates a cardiovascular component on top of the muscular demand. For people who want to add some conditioning to their core work — or who are training for aesthetics and want to elevate calorie burn — the low-rest format serves both goals.
Honest Difficulty Rating
This is intermediate to advanced. If you’re new to ab training, start with the beginner workout above and build for a few weeks before attempting this. If you have a solid training base, this makes an excellent 10-minute finisher after any strength session — the kind that leaves the core genuinely fatigued without eating into recovery for the primary lifts.
