How this HIIT Leg Workout Works

HIIT legs header 1

There are three reasons this HIIT leg workout gets such good results.

1. Big muscles cause excessive results:

Focused resistance training, especially using the legs, unlocks your hormonal and metabolic potential.

It’s well known that you need to “train your legs if you want to grow your arms”.

While the studies available aren’t able to nail down the exact mechanism why this happens, people looking to maximize lean body mass for the whole body should train the legs first.

Kraemer, et al. Hormonal responses and adaptations to resistance exercise and training. Sports Medicine. 2005;35:339–361.

2. Metabolic Supersets create more epoc

You notice that the exercises are in supersets.

A superset is two exercises performed in succession without rest. The secret to getting the supersets right is to train antagonistic muscles, for example, chest and back.

The supersets here are mixing up quads and the glutes for each superset. This technique, commonly known as paired-set training, shows an increase in EPOC and results in greater total energy expenditure when compared to normal weight lifting workouts.

Kelleher AR, Hackney KJ, Fairchild TJ, Keslacy S, Ploutz-Snyder LL. The metabolic costs of reciprocal supersets vs. traditional resistance exercise in young recreationally active adults. J

Even better, supersets increase strength via a phenomenon referred to as “reciprocal inhibition,” or an increase in stored elastic energy in the muscle-tendon complex.

Baker D and Newton RU. (2005). Acute Effect on Power Output of Alternating an Agonist and Antagonist Muscle Exercise During Complex Training. The Journal of Strength and Conditioning Research, 19(1), 202-205

3. Strength + Plyometric Combos burn more energy

As the name implies, combo training is a combination of resistance training and plyometric (or aerobic) exercise.

This is probably the most demanding part of this workout. By the end of the exercises, this workout will break you.

That said: the results are worth it.

There is one problem though: If you want to shove this much leg work into one power packed HIIT workout for legs and have the workout finish in 15 minutes… You will end up working hard.

The advanced version of this workout is 90 seconds of hard work to every 30 seconds of rest, so if you aren’t that fit make sure you start with one of the easier versions.

Yes, you will swear at me the next morning.

How Many Sets Should I Do?

Just one. If you still have energy for another set, your weights are too light and your dynamic exercise is too slow.

How Many Repetitions Should I Do?

Because this is HIIT, the temptation with the strength training exercises will be to go fast. Resist this temptation. Go slowly, pick heavy weights and concentrate on your form. When you move onto the plyometric exercises, go hard and fast. See how many reps you can get in the 30 seconds.

HIIT leg workout for intermediates

How Long Should I Wait Between Exercises?

There is no rest between doing a strength training exercise and a plyometric exercise. They should be down one after another. After the plyometric exercise there is a rest:

  • 90 seconds for beginners
  • 60 seconds for intermediate
  • 30 seconds for advanced

How Much Weight Should I Lift?

This HIIT workout is intense. especially as you move to a more advanced version.

The key of this HIIT leg workout with weights is to use the heaviest you can handle while still maintaining perfect form.

You will get tired quickly so don’t overdo it. Rather start with lighter weights, or even body weight and see how you manage.

You can add heavier weights at future workouts if it becomes easy.
