Your living room makes a convenient gym. There are no membership fees. There’s not a talkative sweaty dude or ripped body-shaming wannabe trainer. No one coughing up a lung on the machine next to you. There’s just you, maybe the kids, maybe some clutter, and just enough floor space. But is a workout at home one that can get you in ripped-and-ready-for-the-world-without-a-shirt shape? Without question. Home workouts become real sweat sessions when you turn off the television, crank some motivational tunes, and give it your all. Here are five hard workouts you can do at home that require the willpower and fortitude — but little to no equipment and minimal space.

Hard Workout #1: Simply Squats and Pushups

This workout has two moves, and seems too simple to be sweat-inducing. To that we say, go ahead, give it a whirl.

Do 21 squats, then immediately do 21 pushups. Rest and repeat with 15 reps each, then 9 reps each. You get two minutes of rest in between sets. That’s it. There’s one caveat for this workout: Your pushup and squat form need to be perfect throughout. That means on the squat, you stand with feet shoulder-width apart, bend knees, and sink down and back like you are about to sit in a chair, aiming to get quads parallel to the floor. In the pushup, you keep a perfect plank in-between the pushups and bring your chest smoothly to the floor and back up without breaking the plank. Sound easy? Sure. Good luck.

Hard Workout #2: 4 Moves, All Out

This workout hits it all in an easy-to-remember, 4-move sequence in which you give each move your all, rest one minute, move on to the next, and then you’re finished. Make that a laying-on-the-floor-in-fetal-position type of done.

Push-Ups: Maintaining form, do as many as you can, as fast as you can, for 20 seconds. Rest for 10 seconds. Go again for 20 seconds. Complete 8 sets of 20 seconds hard/10 seconds rest.

Twist Jumps: Stand with your feet slightly wider than shoulder-width apart and drop into a squat, twisting your torso and arms far to the right as you do. Release arms and torso back to the left as you jump in the air and do a half-rotation to the left. Drop, twist right, jump left again. Do 20 seconds of twist jumping right to left. Rest for 10. Do the next 20 seconds of twist jumps in the opposite direction. Switch sides two more times for 8 sets total.

Reverse Pulses: Start sitting on the floor, legs in front of you, knees bent, feet tucked under a heavy chair for support. Pull your gut toward your belly button and lean back about 45 degrees. Stretching your arms in front of you, begin to pulse up and down as fast as you can, aiming to lean a little further back with each pulse while keeping your abs contracted. Go for 20 seconds. Rest for 10. Do 8 sets.

Mountain Climbers: Get down on the floor in an extended push-ups position, engaging your core and holding your upper body still while you raise one knee to your chest. Then jump it back in place while raising the other. Alternate legs and “jog” your knees to your chest as fast as possible for 20 seconds. Rest for 10 seconds. Do 8 sets.

Hard Workout #3: Climbing Burpees

Here’s another simple two-move workout that will absolutely crush you. The idea here is to do as many of this combination as you can in five minutes, rest one minute, and repeat.

Start in a pushups position. Jump your feet towards your hands, then jump your whole body vertically in the air and back into a crouch. Jump feet back into an extended pushups position. From this position, hike one knee high toward your chest, keeping your hands planted on the floor. Jump it back to the start position, hiking your other knee up at the same time. Continue this alternating pattern of moves for five minutes. Rest one. And repeat. Try to do this three times. Then four. When you can do this five times, well, let’s just say you’re in pretty damn good shape.

Hard Workout #4 The Full Living Room Routine

This 11-part routine is for those days when you’ve got some time to spare and want to mix it up. This is all based on time, so maybe have a smart speaker handy. By the time you’re nearing the end, you might not be able to catch your breath enough to tell Alexa set the timer. That’s a sign it’s working.

Lunges: Warm your body up with lunges — front knee over toe, back leg slightly bent without letting your knee touch the floor, then push back up to standing and repeat with opposite leg. Two minutes total.

Squats: Stand, bend knees, drop seat, resume standing. Repeat. Two minutes.

Jumping Jacks: Get that heart rate up. Two minutes.

Triceps Dips: Find a chair or couch and sit, placing your hands on the edge of the seat. Slide your butt forward until it is off the seat, your weight supported by your arms. Bend and straighten elbows. Three sets of 10 dips.

Wall Sit: Place your back flat against a wall, feet about two feet in front of you. Bend your knees until your quads are parallel to the floor. Stay there for 90 seconds.

Side Plank: Lie on your side, propped up on one elbow and push through your feet to raise your hips off the floor, creating a straight line from your shoulder to your feet. Hold 60 seconds. Switch sides.

Mountain Climbers: Get down in the extended push-ups position, bend one knee to your chest, then straighten it back as you hike the other one up. Continue “jogging” in this fashion for one minute. Rest a minute; do one minute more.

Sit-Ups: Quick on the up, then slowly roll back down. Give us what you’ve got for two minutes.

Calf Raises: Sit in the chair, feet flat on the floor. Lean forward and press down on your quads with your hands. As you do this, rise up onto the balls of your feet. Lower back down. One minute.

Side Push-Ups: Straighten one arm out to the side so that your hand just touches the wall. Keeping your body in a straight line, bend your elbow and lean into the wall. Push away and back to standing. Do one minute on this side, then find the wall on the opposite side of the room and repeat on the other.

Modified Burpees: Start in an extended push-ups position, do a super-fast push-up, then jump your feet towards your hands and stand up tall, feet shoulder-width apart. From here, let your arms drift in front of you while you slowly bend into an easy squat. Hold five counts. Lean forward, drop your hands to the floor, and jump your legs back into a push-ups-ready position. Go again. Two minutes.

Hard Workout #5: The Murph

This classic CrossFit workout pushes the boundaries of living room workout (not to mention fitness sanity). It’s more of a challenge than a workout. It forces you to run outside. It requires a pull-up bar. But if you’re looking to take your workouts to the next level — to get serious about your fitness in a way you haven’t done since high school football — this is your way in.

We suggest trying this out at home and timing yourself for the first few times (spaced out by a month or three; yeah, you’ll need that much recovery) and then working your way up to a public display of the challenge, heading to a CrossFit gym on Memorial Day weekend for The Murph Challenge, where a bunch of loons go head-to-head with this challenge in honor of LT. Michael P. Murphy, the workout’s worthy namesake.

For time:

• Run 1 mile
• Do 100 Pull-Ups
• Do 200 Push-Ups
• Do 300 Air Squats
• Run 1 mile

Note: You don’t have to do this in order. In fact, we suggest that, especially for beginners, you divide it into blocks of, say: 5 pullups, 10 push-ups, and 15 air squats. Be sure to keep a tally on a chalkboard or paper. You will lose track.
