For which exercise are 1 middle spring and 3 repetitions typically used to strengthen the obliques?

The Seated Twist is the exercise chosen for strengthening the obliques with a middle spring and three repetitions. This exercise specifically targets the oblique muscles through rotational movements, enabling increased engagement and strength in this area. By performing the twist while maintaining an upright posture on the mat or equipment, the obliques are activated more effectively, promoting stability and control in the core.

In addition, using a middle spring allows for enough resistance to challenge the muscles without overwhelming them, making it suitable for multiple repetitions. The three repetitions help provide adequate volume for muscle strengthening while ensuring the movements remain controlled and precise.

Other exercises mentioned may also engage the core or obliques, but they either focus on different muscle groups or utilize different equipment settings that do not target the obliques in the same effective manner as the Seated Twist with the specified settings.
