Low-Impact HIIT Workout

Date:


High-intensity interval training (HIIT) is an efficient way to fit physical activity into a busy schedule. However, if you have joint pain or are concerned about your fitness level, low-impact workouts are generally safer. Even if you routinely perform higher-impact workouts, adding low-impact training sessions can help prevent excessive wear and tear on your body and promote recovery.

High-impact HIIT exercises, such as box jumps and plyometric lunges, are excellent for building cardiovascular and bone health, but they can overwork your joints or exacerbate existing joint pain. Plus, higher-impact movements may be too challenging for anyone new—or returning to—exercise. Instead, choose low-impact exercises to avoid sudden movement, jarring, jumping, or other impactful forces on your body. Doing so can help you create a challenging HIIT workout without the risks.

Benefits of Low-Impact HIIT

  • Improved cardiovascular health: Low-impact HIIT challenges your heart and lungs, enhancing your cardiovascular system. This type of workout can help lower blood pressure and improve heart health, contributing to a stronger, more efficient heart.
  • Increased calorie burning: Despite low impact, these workouts are high intensity, which means they’re great for burning calories during and after the session. The dual metabolic process of aerobic and anaerobic metabolism leads to efficient energy use and fat burning, helping to reduce abdominal fat and improve insulin sensitivity.
  • Better overall fitness without straining the joints: Low-impact HIIT minimizes the stress on your joints, making it ideal for people with joint-related issues, arthritis, or those recovering from injury. It’s also beneficial if you want to avoid the high-impact stress associated with traditional HIIT workouts.
  • Enhanced metabolic health: Engaging in low-impact HIIT can make your body more efficient at delivering oxygen to your muscles, improving your metabolic health. This efficiency can lead to better performance in all of your workouts and activities.
  • Psychological benefits: Beyond the physical benefits, low-impact HIIT can also offer psychological advantages, such as reducing stress levels, improving overall well-being, and contributing to a healthier lifestyle.

Warm-Up (5-10 Minutes)

Starting your workout with a warm-up helps prepare your body for the intense exercise to come. A good warm-up will help prevent injury and boost your performance by activating your central nervous system, increasing your body temperature, and promoting metabolic changes.

This preparation phase gives your muscles and tendons a chance to become more pliable, reducing muscular stiffness and improving your joints’ range of motion. Remember, the goal is to activate your muscles and joints gently, so adjust the intensity and range of motion as needed to suit your comfort level and abilities. Here are some activities to include.

Light Cardio

Perform some light cardio to get your blood pumping and warm up your legs, hips, and arms.

HIIT Workout (20-30 Minutes)

This low-impact workout will elevate your heart rate, challenge your muscles, and maximize your workout efficiency through high-intensity interval training (HIIT). By alternating between periods of intense activity and brief rest, you’ll work hard but have moments of rest, each of which you can adjust to your fitness level.

This HIIT workout uses a work-to-rest interval format. If you are a beginner or looking for a less intense session, consider starting with 30 seconds of work followed by 30 seconds of rest. As your endurance improves, you can try a more challenging ratio, like 40 seconds of work to 20 seconds of rest. Listen to your body and adjust as needed.

Complete each exercise for your chosen work period, then rest for your designated rest time before moving on to the next exercise. Repeat the entire circuit two to three times, depending on your fitness level and time constraints.

Remember, the key to HIIT is intensity, so push yourself during the work periods while maintaining good form.

Cool Down

After an invigorating low-impact HIIT workout, it’s worthwhile to conclude with a proper cool-down. Doing so helps gradually lower your heart rate, prevents muscle stiffness, and improves recovery.

When you transition your body back to a state of rest, you also reduce the risk of injury and increase blood flow, which aids in the recovery of the muscles you’ve just worked. A cool-down can also be a peaceful moment to reflect on your workout achievements, setting a positive tone for the rest of your day.

Walk or Pace for 60 Seconds

Begin your cool-down by walking or pacing for 60 seconds to lower your heart rate gradually and start the process of recovery. It’s a simple yet effective way to transition from the high intensity of your workout to the calm of stretching and mobility work.

Static Stretches

Including some static stretches after your workout is a great way to release tension in the muscles that you’ve just worked. Holding each stretch for 30 to 60 seconds allows your muscles to relax and begin the recovery process. Focus on the major muscle groups you’ve used during your workout. Here’s a list of static stretches to try:

  • Quad Stretch: Stand on one leg, pull your other heel toward your buttock, keeping your knees together and pushing your hip forward. Swap legs after 30 to 60 seconds.
  • Hamstring Stretch: Extend one leg out in front of you, toes pointing up. Hinge at the waist and lean forward, reaching toward your toes. Switch legs after holding the stretch.
  • Calf Stretch: Step one foot back, keeping it straight, and press the heel into the ground. Bend the front knee. Switch legs after the hold.
  • Triceps Stretch: Reach one hand down the center of your back, elbow pointing upward. Use your other hand to press on the elbow gently. Repeat on the other side.
  • Shoulder Stretch: Bring one arm across your body and use the other hand to press it into your chest. Switch arms after holding the stretch.
  • Butterfly Stretch: Sit with the soles of your feet together and gently press your knees down with your elbows.
  • Figure Four: While lying on your back, cross one ankle over the opposite knee and gently pull the thigh toward you.
  • Spinal Twist: Lying on your back, bring your knees to one side while keeping your shoulders flat. Switch sides after holding the stretch.

Mobility Work

Post-workout is also an excellent time to focus on mobility work, which can lead to a better range of motion and easier performance of daily activities. Mobility exercises can also enhance blood flow to your muscles and reduce the likelihood of injury. Here are some mobility exercises to incorporate.

  • Cat-Cow: On all fours, alternate between arching your back toward the ceiling (cat) and dipping it towards the floor (cow), moving with your breath.
  • Wall Angels: Stand with your back against a wall, arms raised like a snow angel. Slide your arms up and down, maintaining contact with the wall.
  • 90-90: Sit with one leg bent in front of you at 90 degrees and the other bent behind you, also at 90 degrees. Lean forward over the front leg, then switch sides.
  • Lunge with a Twist: Step into a lunge and place your opposite hand next to your front foot. Twist your torso, reaching the other arm toward the sky. Switch sides.
