The Norwegian 4x4 Protocol is a cutting-edge approach to exercise that can significantly boost your cardiovascular health and stamina. It consists of four intense 4-minute intervals at 90-95% of your maximum heart rate, each followed by a three-minute recovery period. This scientifically backed method is renowned for its efficiency in improving VO2 max and overall endurance. Norwegian 4x4 App is the perfect companion for anyone looking to implement the 4x4 training protocol into their routine.

Hi everyone! After launching a TakeSip.com, a hydration companion as a solopreneur and indie-hacker, I had a burning desire to tackle Norwegian 4x4 protocol, as I have started running myself regularly. Suddenly, it was a greater success than my previous app having a lot of organic traffic and interest. Today I have release a version for Android while iOS app was there in the AppStore for last 2 weeks and grew fast. With this launch, we want to announce a general availability for both mobile platforms and collect customer feedback. Upvote and help us be better! Thank you, dear PH community!
