Whether you’re doing kettlebell swings, deadlifts, or incline sprints on a treadmill, chances are that your trainer or instructor has more than once told you to engage or tighten your core — a step that improves both effectiveness and safety.
To learn how to do this, it’s important to understand what the core is — and what it is not, says Rael Isacowitz, a longtime Pilates instructor, lecturer, and author of the book Pilates.
A tight core doesn’t refer to washboard abs. In fact, visible abdominal muscles play just one (relatively minor) role in a much larger system of muscles that stretch from the upper back down to the hips, around the trunk, and deep inside the body.
The major players of the core are the unseen muscles of the midsection, including the deep-lying abdominal muscles, back extensors, diaphragm, hip flexors, and pelvic floor.
Use the following exercises, recommended by Andrea DuCane, RKC master instructor and author of The Ageless Body, to feel the difference between a tight core and a slack one. You can incorporate them into your workouts to build core strength over time while learning to re-create the engaged tight-core sensation you feel in your workouts.
- Work up to two to four sets of 30-second holds, depending on your experience level.
- Alternate sides, lowering one leg at a time, then try lowering both legs together. Build up to two to four sets of 20 reps.
