| Muscle tension was recorded isometrically under a resting tension of 10 mN as reported previously. |
| Then, isometrically contract the pectoral muscle, attempting to adduct the arm. |
| In passive stretching there is external loading on relaxed or isometrically contracted muscles. |
| The first simulations involved static rigid-beam models, assuming the mandible to be nonflexible and muscles to contract isometrically. |
| Squeeze your contracted muscle isometrically as you complete each rep to intensify the effort and maximize the pump. |
| Your abdominal and erector spinae muscles isometrically contract to stabilize your torso as you move. |
