Train Right With Dynamic Warm-ups

Remember high school gym? Running laps around the track because you mouthed off to the gym teacher was meant to be a punishment, but the joke was really on him.

While you ran around the track and watched your friends stretch their hamstrings, you were doing what’s called a dynamic warm-up. (Well, sort of.)

A dynamic warm-up consists of exercises you do before training that mimic the movements you're going to do while training. These exercises loosen your muscles and tendons, increase blood flow throughout your body, and activate your nervous system so you’re ready for action.

Dynamic exercises are typically better to do before training since static stretches — holding a stretch for a specified amount of time — can lead to injury if done pre-workout. (That’s why they’re better left for after your workout when you need to cool own.)

Now that you’ve grown up and have replaced dodge ball with competitive sport, it’s even more important that you warm up properly.

BEST DYNAMIC EXERCISES TO DO BEFORE TRAINING

Alternating reverse lunge

Stand with your arms at your sides. Squeeze your abs and step backward with your left leg, lowering your body until your right knee is bent at least 90 degrees. Push back into the starting position and repeat with your opposite leg. Do 8 reps on each side.

T-push-up

Start in a standard push-up position with your hands directly under your shoulders, forming a straight line from head to heels. Lower yourself to the ground like a normal push-up. As you push back up, slightly roll your feet, reach your left hand to the sky and make a straight line from one hand to the other.

Return to the push-up position. Lower yourself again, this time pushing up and rotating to the opposite direction. Perform 5 reps on each side.

Single leg RDL

Stand on your left leg with you knee slightly bent. Pick your right foot off the ground. Without changing the bend at your knee, bend at your hips and lower your torso until it’s nearly parallel with the floor. (You can put your arms out to the side for stability if you like.) Your right leg should be off the ground, making a straight line with your body.

Return to the standing position. Do 8 reps on your left leg, then 8 reps on your right.

Side-to-side leg swings

Stand tall and hold on to a chair or other object with both hands. Keeping your right knee straight, swing your left leg as high as you comfortably can out to the side. Swing it back toward your body so it crosses in front of your right leg. That’s one rep. Swing back and forth until you complete 8 reps on your left side. Repeat with your right side for 8 reps.
