12-Minute Low-Impact HIIT Workout For Bad Knees

My 12-minute low-impact HIIT workout for bad knees is designed to be gentle on joints while providing an effective cardio and strength workout, perfect for all fitness levels.

So you want to do some high-intensity interval training (HIIT), but your knees are in rough shape? Can you even do HIIT with bad knees? The answer is yes!

You can do low-impact HIIT that won’t aggravate knee pain. High intensity does not have to mean jumping. You can be high-intensity but perform low-impact exercises. 

HIIT workouts encourage you to work hard during the work segment and then take a break to quickly recover during the rest segment.

So, even if you can’t jump or do deep squats and lunges, this low-impact HIIT workout for bad knees will still help you reap the benefits that high-intensity interval training provides, such as:

• A higher rate of fat burn both during and after the workout
• Building your cardiovascular endurance
• Raising your metabolic rate
• Working smarter, not longer

This workout was designed using moves that are protective of bad knees, some of which include holding dumbbells to give you that extra push of high intensity. And because it is low impact, you could do a workout like this daily. Ready to get started?

Performing push-up renegade rows strengthens your upper body and core, enhancing muscle tone and stability.

How To Perform Push-Up Renegade Rows:

2. Lower your body in a straight line toward the ground to a low plank without sagging your back, then push back up to plank.
3. Pull right dumbbell up toward right hip bone, keeping weight close to your side. Slowly return it to the floor. Repeat the push-up and pull the left dumbbell to the left hip bone. Continue the push-up row alternating sides.

3. Lateral Shuffle

The lateral shuffle boosts cardiovascular endurance and agility, targeting the lower body and core.

How To Perform a Lateral Shuffle:

1. Start standing with feet hip distance apart, slightly bend knees and sink your weight back into your heels so you don’t feel it in your knees. Bring both hands in front of the chest in guard position.
2. Start with right foot moving right and left foot following. Shuffle right for four right-left steps, then move left for four left-right steps. Continue shuffling right/left for the desired amount of time.

Go for 30 seconds. Transition to next exercise in 15 seconds.

4. Sit-Up Press

The sit-up press engages your core and upper body muscles, promoting strength and coordination.

How To Perform a Sit-Up Press:

1. Start on back with bent knees and feet on the mat. Elbows are bent and dumbbells are resting above the chest.
2. Bring the head, neck, and shoulders off the mat sitting up, and extend the arms out long pressing the dumbbell forward. Return back to the mat with control.

Go for 30 seconds. Transition to next exercise in 15 seconds.

5. Punching

Doing this punching exercise increases cardiovascular fitness and upper body strength while improving hand-eye coordination.

How To Do Punching:

1. Stand with feet slightly wider than shoulder-distance apart and bend knees slightly. Tighten the core to keep your center still.
2. Punch out one arm at a time at a steady, intense pace.

Go for 30 seconds. Transition to next exercise in 15 seconds.

6. Squat and Curl with Alternating Knee Lifts 

The squat and curl with alternating knee lifts tones the legs, arms, and core, while enhancing balance and coordination. If balance is something you struggle with, try these balance exercises that help at any age!

How To Perform Squat and Curl with Alternating Knee Lifts:

1. Start in squat position, weight back on heels and arms long next to side holding dumbbells.
2. Squeeze your glutes to press up and lift right knee as you curl the weights to your shoulders.
3. Slowly lower the weights back down and return to squat position.  Repeat with left knee.

Targets: biceps, glutes, quads

7. Army Crawl

The army crawl strengthens the core, shoulders, and upper body, improving overall muscular endurance.

How To Perform An Army Crawl:

1. Begin in a plank position with your shoulders over your wrists, your feet together, and your body in a straight line.

3. Then bend your right arm so you are in a full forearm plank position.
4. Lift your left hand and place it on the mat directly below your shoulder as you push through your palm to lift yourself.
5. As you reach the top, place your right palm on the floor under your right shoulder and push back into a full plank. Repeat, leading with the right arm.

Go “forearm forearm hand hand” for 30 seconds, moving at an intense pace. Transition to next exercise in 15 seconds.

8. Knee Thrust

Performing knee thrusts activates the core and lower body muscles, boosting cardiovascular fitness and agility.

How To Perform Knee Thrusts:

1. Start standing with feet wider than shoulder distance apart and turn both feet in one direction allowing the hips to follow like you’re in a shallow lunge. The front knee is a 90-degree angle and the back heel lifted. Arms are in guard position in front of the chest.
2. Drive the back knee up to hip height towards the hands, and hands in towards the thigh. Return the foot to floor and repeat.
