Plank Challenge 4 minutes is a lifestyle app available on the iPhone platform. Developed by Bo Kalvslund, this free app falls under the Health & Fitness category.

The app focuses on strength training, specifically targeting the abs, back, and arms through the plank exercise. The training program is designed to help users achieve a 4-minute plank after 5 weeks of consistent exercise.

The program consists of 4 days of training followed by a 3-day break, allowing the muscles time to develop. This approach emphasizes intensive strength training in short periods of time, minimizing the risk of injury.

In addition to the plank challenge, the app also offers the option to track and increase the number of push-ups at your own pace, ranging from 1 to 100.

One notable feature of Plank Challenge 4 minutes is its integration with Apple Music, allowing users to continue their music seamlessly even if interrupted during the workout.

Take on the challenge and improve your core strength with Plank Challenge 4 minutes!
