Jennifer Aniston's trainer, Dani Coleman, reveals the star's love for plank variations, emphasizing their effectiveness in building strength and stability. The plank-to-pike move, performed on gliders, is a 10-minute exercise that combines strength, stability, and coordination. While it may look daunting, the move is incredibly effective, even in short bursts. Fitness professionals agree that the plank-to-pike move is a full-body exercise that targets multiple muscle groups, including the abdominals, shoulders, upper back, and arms. The addition of gliders increases the demand on stabilizing muscles, making it a functional way to build strength. For beginners, Tara Riley suggests a modification called the 'plank to hover' move, which is a more accessible version of the exercise. Ultimately, consistency is key to seeing results, and incorporating core work into a balanced strength program is far more effective than cramming it into one session.
