If you're trying to lower your bottom blood pressure number, going for a steady, moderate workout might work better than doing short, intense sprints — especially if those sprints last 30 seconds or more.

If you're trying to lower your bottom blood pressure number, going for long, steady jogs might work better than short, intense sprints — especially if you're only doing the sprints for less than 8 weeks.

Both short, intense sprints and steady, moderate workouts can slightly lower your resting blood pressure—and they work about the same for people who don’t exercise much or have normal blood pressure.

Doing short bursts of all-out exercise for at least 8 weeks might lower your top blood pressure number more than steady, moderate workouts—especially if each burst is under 30 seconds.

Doing steady, moderate workouts might boost your heart and lung fitness more than super intense but short sprints, even though the moderate workouts take longer.

Short, intense bursts of exercise (like sprinting) can boost heart and lung fitness just as well as longer, steady workouts — and take way less time.
