The key to learning to sprint is to start with these nine steps high-intensity training, and I wanted to ask about proper form during the sprints. Is it different from proper form during easy running/jogging or merely a sped-up version of it? In other words, do I consciously alter my posture, movement range, etc., during sprints?

The short answer is it’s both the same and different. The movement patterns of running and sprinting are similar in that you need to put one foot in front of the other, but sprinting is a more dynamic version of running (more explosive, to be precise).

If you compared them on a continuum, walking and easy jogging would be on the left side, while sprinting would be on the far right. Both will get you from point A to B by landing right, left, right, left; however sprinting requires more power and muscle activation to cover the same stretch of road.

to further prepare your body to run fast

Another difference between jogging, running and sprinting is foot strike. When walking, jogging, and running most runners land with a heel strike. The faster you run, the more you shift from heel strike to mid-foot to a forefoot landing.

drills like high knees, butt kickers and skipping:

1/ Warm up

The harder you run, the more vital it is to warm up your muscles. Walk and easy run for five to 10 minutes and include dynamic exercises or Runners World, Part of the Hearst UK Wellbeing Network I read your column about.

2/ Focus on posture and core

Keep your torso upright, shoulders relaxed and away from your ears, and engage your core (don’t collapse). Unleash your Superman pose.

3/ Run with a circular motion

Think like a cyclist and move your feet in a circular motion, raising your thighs up until they are parallel to the round, and driving your knees up and down (rather than an ovular or reaching-out motion).

4/ Land efficiently

Land on your forefoot and focus on pushing off from your toes to propel yourself forward and keeping your feet flexed upward toward your shins.

5/ Perform rolling starts

Hold your arms in a bent position (90 degrees) and drive the elbows backward to create momentum. This is a more exaggerated arm swing than a jog, where your arms move through a wider range of motion with your hands coming up as high as your chin and backward toward your butt.

6/ Drive your arms

Long strides are energy wasters. Focus on cadence speed rather than distance as you sprint. You'll run faster and more efficiently by taking How to train for elevation, according to Tom Evans.

7/ Kick butt

As you push off from the forefoot and toes, bring your heels up toward your butt.

8/ Breathe

Relax and sync your breathing to the rhythm of your feet. You’ll reduce wasted energy from muscle tension.

9/ How to run 100 miles

Perform this drill to feel the difference between walking, jogging, running and sprinting. Start by walking, and increase your speed every 10 seconds until you reach a sprinting speed.

As with anything in the high-intensity world, a little goes a long way. Work into high-intensity sprint training gradually to allow your body to adapt to the demands of the workout, and stick with it to see improvements in your running fitness and overall health.
