20-Minute HIIT Workout at Home (No Equipment): 3 Levels

"HIIT workout at home" searches grew 70% last year, and "full body HIIT workout" grew 40%. It makes sense: HIIT needs no equipment, little space and little time. You can train effectively in a living room in 20 minutes.

Here's a complete 20-minute home HIIT workout at three levels, plus a quiet version for apartments and a plan to progress.

The short answer

• Format: 40 s work / 20 s rest, 5 exercises per round, 3–4 rounds, 1 min rest between rounds.
• Time: ~20 minutes including warm-up.
• Frequency: 2–3 times a week, on non-consecutive days.
• Choose your level below and move up when it feels manageable.

Warm-up (4 minutes)

Do each for 40 seconds:

1. Marching in place with arm swings
2. Bodyweight squats (slow)
3. Arm circles + shoulder rolls
4. Hip hinges (hands on hips, push hips back)
5. Easy step-jacks (step out and in)
6. Inchworm walkouts

The workout: pick your level

40 s work / 20 s rest per exercise, 5 exercises = 1 round (5 min). Rest 60 s between rounds.

#	Beginner (low impact)	Intermediate	Advanced
1	Squat to calf raise	Squat jumps	Tuck jumps
2	Incline push-up (hands on sofa)	Push-ups	Push-up to T-rotation
3	Standing knee drives (fast)	Mountain climbers	Burpees
4	Reverse lunges (alternating)	Jumping lunges (alternate reps)	Jumping lunges
5	Plank shoulder taps (knees down OK)	Plank shoulder taps	Plank jacks
Rounds	3	3–4	4

Effort: the work intervals should feel hard (about 8/10) by the second half of each round. If you're chatting, go faster. If form breaks down, slow down. New to intervals? Start with HIIT for beginners.

Quiet version (apartment-friendly)

No jumping, but still hard:

1. Tempo squats: 3 s down, fast up
2. Push-ups (or incline)
3. Slow mountain climbers with a knee-to-elbow touch
4. Reverse lunge to knee drive
5. Bear crawl hold with shoulder taps

Push the pace and keep rests strict. Your heart rate will still get high.

Cool-down (3 minutes)

Walk around for 60 s, then 30 s each: hamstring stretch, quad stretch (each leg), chest-opener against a wall, child's pose.

How to progress over 6 weeks

Weeks	Change
1–2	Beginner or intermediate level, 3 rounds, 2× per week
3–4	Add a round or switch to 45 s / 15 s
5–6	Move up a level on 2–3 exercises or add a third weekly session

Progress one variable at a time: rounds, work-to-rest ratio or exercise difficulty. That's the same progressive overload principle you'd use with weights.

• Compare with steady cardio: HIIT vs cardio
• Add weights: a single kettlebell makes home HIIT much harder. See kettlebell workouts

Pair it with strength training

HIIT at home is great for conditioning, but it builds limited muscle. For the best results, combine 2 HIIT sessions with 2–3 strength sessions per week. With no equipment, a calisthenics plan works well. See HIIT and weight training for scheduling.

Track your rounds and reps

Count your reps in each 40-second interval (e.g. push-ups, burpees) and write them down. Next week, beat them. It's a simple way to see your conditioning improve.

GymMonster keeps your workouts and personal records in one place, so home HIIT days and strength days count toward the same visible progress.

The bottom line

A 20-minute home HIIT workout of five exercises, 40 s on and 20 s off, for 3–4 rounds is enough to build real fitness with no equipment. Choose your level, keep the work intervals hard, progress one variable at a time and do it 2–3 times a week alongside some strength training.
