Increase speed

*Obviously in a hurdle race you want to go as fast as possible using our fast-twitch muscles, to increase your speed it is important to have the right running form, it's also important to not overstride, and keep the form while running over the hurdle

*In this demostration my right leg will be my lead leg and my left leg will be my trail leg, but that can change deppending on the hurdler.

Lead Leg

*After obtaining enough velocity and have approach to the hurdle the right distance, push off the floor with your trail leg using you quads, gastrocnemius, and soleus to mane a few muscles. In my case it would be my left; some hurdlers use the other leg.
*You push off with your trail leg and bring your other leg, which is the lead leg, in my case my right, foward and make it straight, parrallel to the ground, aiming just above the hurdle.

Attack hurdle

*As you attack the hurdle, focus on bringing your lead leg (right) straight just above the hurdle, at the same time,  you push off the floor with your trail leg (left) off the floor to start bringing it up. Make sure your upper limbs are in right form and your torso is leaning foward.

trail leg

*At this point your lead leg (right) is on top of the hurdle, momemtum is going to keep you going foward so focus on bringing your trail leg (left) to it's right form; Your knee will be flexed and your leg abducted, next to your hip, parallel to the floor. At this point you will reach the apex point

mid-air form

*This would be the climax, your center of gravity will be above the hurdle. At this point make sure to keep your running form, lead leg (right) straight, trail leg (left) bent parrallel to the floor, with your torso leaning foward.
*Remember to keep your running form.

trail leg foward

*Following the climax, bring your lead leg (right) down to the floor, this will happen automatically due to gravity, but at the same time start bringing your trail leg (left) infront of you to use it as your next step foward using with full range of motion.

Trail leg next step

*When landing on the ball of your foot with lead leg (right), push off of it to help bring ur trail leg (left) foward, making it ur next step to increase momentum.

Keep momentum going


*After landing and pushing off with the lead leg, make sure to keep the momemtum going this way speed is not lost by maintaining velocity.
