Summary

Scientists compared two types of exercise: very hard but super short workouts (SIT) and easier but longer ones (MICT), to see which is better for heart health and fitness.

Surprising Findings

MICT lowered diastolic blood pressure significantly (−2.11 mmHg), while SIT did not (−0.75 mmHg), despite both improving systolic pressure.

Many assume high-intensity exercise is superior for all cardiovascular markers, but here, moderate effort wins on a key measure.

Practical Takeaways

Try 8 weeks of sprint training with under-30-second bursts to maximize blood pressure benefits.
