More strength for a stronger heart
Why targeted training improves your heart health
Have you ever wondered how you can train your heart specifically – without hours of endurance training? Your heart is the only muscle that never rests. And like every muscle, it needs specific stimulation to stay strong. Especially as we get older. High-intensity interval training using the 4x4 method specifically strengthens your heart muscles. In just 35 minutes per week, you can improve your heart's pumping capacity, boost your oxygen uptake and gain more endurance for an active, self-determined life.

Cardiovascular training: The concept for a strong and healthy heart
Experience a highly effective interval training program that directly supports your heart health. The 4x4 HIIT consists of four high-intensity intervals of four minutes each, followed by four minutes of recovery. This method enhances your heart fitness – efficiently and effectively.
Efficient cardiovascular training
Short, intense bursts of exercise quickly get the cardiovascular system going and promote fatigue resistance.
Improved cardiovascular performance
Regular interval training strengthens the heart muscle, improves blood flow and lowers the resting heart rate.
Increased oxygen uptake (VO₂max)
Intense intervals challenge the body to take in and use more oxygen – a clear benefit for your performance.
Improved blood circulation and heart function
The training increases vascular elasticity, promotes blood circulation and supports efficient heart function.
Supports sugar and fat metabolism
Short, intense bursts of exercise improve insulin sensitivity and promote fat burning – ideal for preventing obesity and type 2 diabetes.
Effective, scientific and sustainable
The formula: 1x35 minutes per week
A strong heart in just 35 minutes per week: with the proven 4x4 HIIT method, you can increase your performance and strengthen your heart health – in a time-saving and evidence-based way.
