20-Minute Fat-Burning HIIT Workouts (No Equipment)

HIIT That Actually Fits Your Schedule

When time is slim, HIIT keeps your conditioning sharp without endless hours on cardio machines. These 20-minute workouts use strategic intervals to maximize intensity while protecting joints, hormones, and recovery. Rotate them through busy weeks, stack them with strength days, and lean on low-impact options whenever needed. The goal: move with power, not punishment.

Quick Warm-Up Flow (3 Minutes)

• Marching high knees with arm swings – 45 seconds
• World’s greatest stretch with rotation – 45 seconds
• Bodyweight squats to calf raise – 45 seconds
• Inchworm walkouts – 45 seconds

Finish with 2-3 rehearsal reps of the first workout move so your nervous system is ready.

Workout 1: Total-Body Torch

Structure: 30 seconds work / 15 seconds rest, repeat circuit 4 times.

• Squat to alternating reverse lunge (low-impact: bodyweight squat only)
• Plank jack + shoulder tap (low-impact: step jacks + shoulder tap)
• Skater bounds (low-impact: lateral toe taps)
• Glute bridge march

Finish with 60-second dead bug hold to reinforce core control.

Workout 2: Athletic Core Burn

Structure: EMOM (every minute on the minute) for 16 minutes.

• Minute 1: 12 alternating sprinter lunges + 8 knee drives
• Minute 2: 10 plank shoulder taps + 10 plank toe taps
• Minute 3: 15 mountain climbers + 10 frogger hops (step out for low impact)
• Minute 4: 20 Russian twist taps (seated knee drives if needed)

Rest any leftover time within the minute. Focus on crisp reps, not speed.

Workout 3: Plyo Power Pop

Structure: 40 seconds work / 20 seconds rest, 3 rounds, 1-minute rest between rounds.

• Power skip or march with knee drive
• Fast feet drop (alternate low drop to squat)
• Push-up to shoulder tap (incline for modifications)
• Hollow body rock or bent-knee hold

Keep landings soft and use arms to drive momentum. Choose the low-impact option if form breaks down.

Workout 4: Tabata Ladder

• Pair A: Jump squat ↔ Alternating step-back lunge (low-impact: air squat ↔ step-back)

Rest 60 seconds between pairs. Total time including rest: 15 minutes plus warm-up/cool-down.

• Step squat with knee drive
• Bear crawl hold with reach (alternate arms)
• Glute bridge to march

Perfect for luteal phase, active recovery days, or when joints need a break.

Cool Down (2 Minutes)

• Forward fold with sway – 45 seconds
• Half-kneeling hip flexor stretch – 45 seconds each side
• Box breathing (inhale 4, hold 4, exhale 4, hold 4) – 60 seconds

Recovery and Rotation Tips

• Alternate HIIT days with strength sessions like the compound lift guide or lower-body power program.
• Hydrate post-workout and refuel with 20-30g protein plus complex carbs.
• Adjust intensity during late luteal or menstrual phases by choosing low-impact options and reducing rounds.
• Track resting heart rate or perceived exertion to avoid burnout. If numbers climb, scale back for a week.
