How Stretching Improves Performance in High-Intensity Workouts

Do you jump straight into a high-intensity workout without stretching? While skipping stretches may be common, but stretching benefits in workout routine can’t be overlooked. It may require few minutes of your time, but the benefits are worth the effort. Stretching benefits in workout involves preparing the body for intense movement as well as supporting better recovery.

High-Intensity Interval Training (HIIT), as known, helps in stimulating metabolism, burning calories, improving cardiovascular strength and building lean muscle mass. It strengthens the core muscles in the hips, buttocks, thighs and arms.[1]Since the intensity of HIIT places significant pressure on your muscles, joints and the connective tissues, including warm up exercises prior and a cool-down session after, is essential for every HIIT workout.

Whether you’re a beginner or a seasoned fitness enthusiast, including stretching for performance and to develop and maintain optimal fitness is crucial. Let’s delve further into understanding stretching, its types, benefits, the right stretching exercises that can be incorporated before and after training and related aspects affecting overall health.

What is Stretching?

Stretching is a physical exercise that requires putting a body part in a certain position that involves lengthening and elongation of the muscles and soft tissues.[2] Stretching benefits in workout routine by improving flexibility, mobility and, as a result, the range of motion of your joints.[3]

Better flexibility training benefits you in the following ways: 3

  • Increase blood flow to the muscles.
  • Enable your muscles to work more effectively, reducing tightness and stiffness.
  • Help your joints move through their full range of motion. Thereby, making it easier to perform exercises like lunges and squats with ease.
  • Reduce the strain on muscles and joints.
  • Support better balance and coordination during high intensity HIIT movements.

The major areas of the body that help with mobility need to be focused during stretching. These include your calves, hamstrings, hip flexors and quadriceps. For upper body relief, opt for moves that stretch the shoulders, neck and lower back.[4]

Types: Dynamic Vs. Static

  • Dynamic stretching: It involves preparing your body for the physical demands of a high-intensity workout with active movements that take your muscles and joints through their full range of motion.[5] These stretches elevate heart rate and improve flexibility and mobility, making them ideal warm up exercises. Some examples of dynamic stretches include leg swings, arm circles, walking lunges, high knees and hip circles. If you are stretching for performance, these stretches can be effective as they closely resemble the exercises performed during the HIIT workout and also help to reduce the risk of injury.
  • Pre-workout techniques: Begin with controlled movements, spending about 5-10 minutes on dynamic stretching and then gradually increase the intensity.
  • Static stretching: It requires you to move a muscle as far as it can go to an extent where you don’t feel any pain and hold the muscle in that fixed position for 20 to 45 seconds.[6] It is commonly preferred as a part of your cool-down routine after high intensity workout. These kinds of stretching, benefits in workout by helping you restore muscle strength and promote relaxation. Static stretches include hamstring stretch, quadriceps stretch, calf stretch, hip flexor stretch, chest and shoulder stretch. Repeating each static stretch two to three times consistently can lead to better flexibility.
  • Post-workout technique: Breathe steadily and slowly throughout the stretch. Avoid bouncing or jerky movements, as they can increase the risk of muscle and tendon strain.

 Benefits of Stretching for Performance

  • Improves flexibility to prevent injury:[7] Engaging in regular flexibility training benefits by reducing the risk of muscle imbalances. When muscle imbalances occur, the body becomes resistant to perform various body movement patterns. This leads to poor posture, which in turn causes improper movement and form, increasing the risk of injury.  
  • Increases mobility: Flexibility training benefits joint mobility, by allowing the body to move freely through its full range of motion. As a result, it helps you perform HIIT exercises with better form and less stiffness.
  • Supports proper exercise technique: With adequate flexibility and mobility, you are able to maintain correct form while doing HIIT exercises. While stretching for performance, maintaining a good technique is also essential to improve exercise efficiency and helping reduce unnecessary stress on muscles and joints.

Best Stretching exercises for HIIT

Here are a few stretching exercises with the target muscles and duration mentioned:

Before HIIT (Dynamic exercises)

These warm up exercises prepare the body by activating the muscles and helping you perform more efficiently.[8]

  • Leg swings (10-15 swings, hip flexor i.e. back leg, glutes and hamstrings): Stand next to a wall or chair for support and swing your one leg forward and backward in a controlled manner.
  • Arm circles (10-15 circles in each direction, shoulders):  Extend your arms out to the sides and make small circles with your hands, gradually increasing their size.
  • High knees (20-30 sec, hip flexors, calves, quadriceps i.e. front thigh muscles and core): Run in place by alternately lifting your knees up towards your chest while pumping your arms in controlled manner.

After HIIT (Static exercises)

A focused 5-10 minutes can serve as a simple full-body routine to get you started.

  • Standing Forward Fold (1 minute, hamstrings and lower back): With your feet hip-width apart. Relax your head and neck, allowing them to hang naturally towards the floor and feel the stretch in your hamstrings and spine.
  • Low Lunge (30 seconds, hip flexors and quadriceps):  Step one foot forward into a lunge, placing the knee of your rear leg on the floor. Gently tuck your tailbone and slightly shift forward with your hip.
  • Child’s Pose (1 minute, back, shoulders, hips):  Kneel on the floor extending your arms forward, sit with your hips as close to your heels as possible and rest your forehead down on the ground.

Stretching benefits in workout aren’t just limited to increasing overall fitness and performance. It also helps improve the quality of life as better flexibility gives you the freedom to perform daily activities easily as you age. Thus, when combined with proper exercises, techniques and timing, you are equipped to train harder and recover smarter in high intensity workouts.
