6-minute cardio: This quick workout will really make you sweat.

This short bodyweight workout sends your heart rate soaring while also helping to kick-start fat burning.

If you can’t face a treadmill or a jog round the block, a punchy interval training session can deliver a very similar effect - and you don’t need any equipment. The concept is simple: a tight blend of strength and cardio drills using only your bodyweight. You can complete it in six minutes, but it’s just as easy to extend it to 20 minutes.

6-minute cardio workout: how the mini-workout works (bodyweight HIIT)

The set-up is straightforward, which makes it easy to fit into everyday life. All you need is a mat, a bit of floor space, and a timer on your phone.

Five movements, short intervals, high intensity - that’s the idea behind this mini-workout.

Basic structure

• 5 exercises performed back-to-back
  
• each exercise is done for time, not for reps
  
• work and rest alternate

Interval options

Training level	Work time	Rest time	Recommended rounds
Beginner	20 seconds	40 seconds	2–3 rounds
Base version	30 seconds	30 seconds	5 rounds (approx. 6 minutes)
Advanced	45 seconds	15 seconds	3–4 rounds (18–24 minutes)

One round means completing all five exercises once in sequence. If you’re short on time, do a single round. If you want to push your limits, string together multiple rounds - similar to how interval running builds effort and recovery into one session.

The five exercises in detail

1. Lateral lunge with knee drive (right side)

Stand with feet about hip-width apart. Take a big step out to the side, sink into a lateral lunge, then drive powerfully back to the centre. At the end of the movement, pull the outside knee up briskly.

• keep your back tall with your chest gently lifted
  
• shift your weight onto the working leg
  
• brace your core so the knee lift stays controlled
  

2. Lateral lunge with knee drive (left side)

Perform the same movement on the other side.

In the workout, you can split sides (for example 30 seconds right, 30 seconds left) or alternate sides smoothly as you go.

Progressions:

• A bit harder: add a small hop as you lift the knee.
  
• Even harder: touch the floor with one hand at the bottom of the lunge.

3. Walk-out to plank with press-up and jump

Start standing. Fold forwards, place your hands on the floor, and “walk” your hands out until you reach a strong plank. Do a press-up, then bring your feet back towards your hands and jump up powerfully - adding a 180-degree turn so you land facing the opposite direction.

• Easier: skip the press-up and simply walk out to a plank.
  
• Harder: make the jump more explosive, similar to a half-burpee.

This move hits shoulders, chest, core and legs, and it noticeably drives your heart rate up.

4. Side-to-side “tyre” jumps

Imagine a large tyre lying on the floor next to you. Stand side-on to it and jump back and forth over the imaginary tyre with both feet at the same time.

• keep a slight bend in your knees and land softly
  
• lift your knees actively to ramp up intensity
  
• swing your arms to stay balanced
  

Milder option: instead of one big jump, take two quicker side steps or small hops. Your pulse stays high without tipping you straight into overload.

5. Commando burpees

This variation takes things up another notch. From standing, move into a plank and lower your body all the way down to the mat. Press back up, then drive your knees in towards your chest one at a time, bring your feet up to your hands (either stepping or with a small jump), stand tall, and finish with a jump and a slight turn.

It’s tough - but highly effective:

• works almost all major muscle groups
  
• elevates your cardiovascular system quickly
  
• develops coordination and full-body tension
  

How to get the most out of the training

The biggest lever isn’t any single exercise - it’s consistency. Even six minutes, done several times a week, can make a real difference.

If you build this mini-workout into your routine, you can significantly improve fitness, strength and calorie burn - despite the short duration.

A few simple rules will help you train safely and effectively:

• Technique before speed: move well at a slightly slower pace rather than rushing with poor form.
  
• Control your breathing: aim for steady inhales and exhales; don’t hold your breath.
  
• Active rests: don’t sit down in the breaks. Walk around lightly, roll your shoulders, breathe deeply - let your heart rate come down under control.
  
• Warm-up: spend 3–5 minutes warming up with gentle hops, arm circles, knee lifts or star jumps.
  
• Cool-down: walk it off briefly, then add a few stretches for legs and back.
  

To keep the intensity honest, choose a pace where you can maintain good form but you’re still working hard by the final few seconds of each interval. If you’re able to chat comfortably throughout, it’s probably too easy; if you’re losing technique immediately, scale it back and build up over time.

What this mini-workout can do for you

The approach is based on HIIT (high-intensity interval training). Short, demanding bursts alternate with brief recovery periods - and it’s this contrast that creates the training effect.

• Better endurance: your heart and lungs adapt to rapid changes in effort.
  
• Higher calorie expenditure: the high intensity keeps your metabolism elevated for a while after training.
  
• Stronger muscles: legs, glutes, core and arms contribute in almost every drill.
  
• Everyday fitness: jumps, plank work and quick direction changes improve stability and resilience in daily life.
  

For many people who don’t get on with jogging, this mix of jumps, support positions and full-body moves is a welcome alternative. You’ll be out of breath without needing to loop round the park.

Fitting the plan around your week

Especially when you’re starting out, you don’t need a perfect plan. It’s more useful to begin small and build up based on how you feel.

• Start with 2–3 rounds using the easiest timing option.
  
• When you feel confident, increase work time first, rather than adding lots more rounds straight away.
  
• Later, slot it into your week - for example Monday, Wednesday, Friday.

Example week:

Day	Session
Monday	6-minute workout, beginner intervals
Wednesday	3 rounds of the base version (approx. 9 minutes)
Friday	4 rounds of the base version, or two tougher rounds

If motivation is a challenge, pick a consistent trigger (for example, “after I make my morning coffee” or “as soon as I get home from work”) and keep the barrier to entry low: mat down, timer set, start. The simplicity is part of what makes this format so sustainable.

What else to bear in mind

Interval training places significant demands on your body. If you have cardiovascular issues, serious joint problems, or you’re returning after a long break from exercise, it’s sensible to get medical advice before starting. Jumping can stress the knees and ankles, especially on hard floors.

A few easy modifications can reduce risk:

• swap jumps for quick steps
  
• use a smaller range of motion (for example, shallower squats/lunges)
  
• wear trainers with good cushioning
  
• if pain appears, slow down immediately or stop
  

If you’re already reasonably trained, you can also combine the 6-minute block with a strength session: do the interval workout first, then add a short legs or core focus afterwards. That way you can put together a fairly complete workout in around 30 minutes.

Terms like HIIT can sound technical, but in practice it simply means: short, hard effort, short rest, repeated. That’s exactly what sits behind this mini-workout - and it’s why you can achieve a lot in very little time, as long as you commit to the intervals and stick with it for several weeks.
