Part 3/7:
Shelly emphasizes that all exercises can be modified based on individual fitness levels. The workout progresses gradually from basic leg movements to more challenging core engagements. One notable exercise is the seated run, which engages the core effectively while keeping impact low. Participants are encouraged to lean forward, as if running without moving their feet, maximizing core activation during the 10-second burst.
As the session unfolds, viewers find themselves performing various exercises such as side twists, toe taps, and knee lifts. Each movement focuses on the abdominal muscles, but also incorporates other body parts, promoting a holistic workout. The emphasis is on using one's abdominal muscles for lifting and stabilizing — key components in strengthening the core.
