Why Is HIIT Good For The Lower Body And Legs?

HIIT stands for High Intensity Interval Training and is, rightly so, an incredibly popular workout format in both fitness classes and individual exercise sessions. It involves intense bursts of activity followed by rest periods and is a great way to get maximum value from a shorter workout. HIIT often involves bodyweight exercises, but many people opt to use weights in their HIIT workouts. 

HIIT can give a fantastic workout for the whole body, helping to boost fitness and torch calories (you can learn more about the benefits of HIIT in more detail here). However, it can be adjusted to focus more closely on specific areas of the body, like the lower body and legs. 

Here are just a few of the benefits that lower body HIIT could have on your fitness journey: 

  • Builds muscle and strength: many common HIIT exercises, such as squats, lunges, burpees and jump squats, heavily involve leg muscles like the quads, hamstrings, glutes and calves. These compound movements engage and build several muscle groups at the same time, helping to increase strength, tone and bulk your legs.

  • Improves endurance: targeting the lower body in your HIIT workout will make you less likely to suffer from the ‘jelly legs’ sensation that can be common after leg days. Challenging the muscles to perform at high intensity for a short duration can lead to improved muscular stamina over time.

  • Boosts cardio fitness: HIIT is not just about strength, but also cardiovascular fitness. The cardio benefits of HIIT improve blood flow to the lower body, which can enhance overall leg health.

  • Allows for variety: The HIIT format can be applied to various exercises, which helps to keep workouts interesting and prevents plateaus. You can incorporate exercises that specifically target the lower body and legs or create a full-body HIIT workout that includes lower-body movements.

Is HIIT A Good Approach For A Lower Body Workout?

There are many things to consider when planning leg day or lower body focused workouts, including:

  • What muscle groups you want to target. Do you want to work all the lower body muscles or split them up into different workouts like this hamstring and glute workout or these glutes exercises for women.

  • What goal you want to achieve. Are you trying to build strength, increase endurance, improve body composition, or something else? Different goals will have different ideal workouts.

  • How much time you have to work out. If you only have a short amount of time to work out, you’ll need to prioritise compound exercises and shorter rest times.

  • What equipment you have. What do you prefer to use, and what will help you reach your goals. You might even base your workout around specific equipment, like this barbell lower body workout or this free weights leg workout.

A HIIT leg workout can be a great approach for lower body workouts for multiple reasons:

  • It allows you to get an effective workout in a short amount of time, thanks to the interval training format and focus on compound exercises.

  • It helps to build muscle and strength while burning fat, ideal for improving body composition.

  • It can use minimal (and even no) equipment, so can be done at home as well as the gym.

  • It works the cardiovascular system and helps to improve overall fitness.

HIIT workouts work well in a weekly schedule alongside resistance training, so depending on your goals, you may want to combine lower body HIIT workouts with other leg workouts throughout the week. For example, you could do one longer leg workout with a mix of compound exercises like barbell squats and isolation exercises like leg extensions, and one lower body HIIT workout.

The Best HIIT Workout For Lower Body And Legs

Ready to incorporate some HIIT into your routine? Here’s a lower body HIIT circuit of eight gym exercises you can try out.

Including time for a warm up and cool down, this should take you just over half an hour in total and will give you an effective, well-rounded lower body and leg HIIT workout. 

For this plan, you’ll work through the eight exercises all the way through, three times. In the first round, you’ll complete each exercise for 45 seconds, for round two it’ll be 60 seconds and the final round will be 75 seconds for each movement. 

There will be no rest intervals between exercises, but you can take 60 seconds to recover between each round. 

Warm up first with some light movement (jogging on the spot, high knees etc) and cool down afterwards with some easy static stretching across all muscle groups.

Aim to complete as many reps of the following exercises as you possibly can within the time limit for a powerful HIIT leg workout.

  3. Kettlebell Swings:

  4. Kettlebell Romanian Deadlifts (RDLs):

    • Perform a regular bodyweight squat, then explosively jump into the air as high as you can.
