Primal At-Home Workout: Core

Mark Sisson doing a plank outsideGyms all across the world are closed right now. Many of us are stuck at home, unable or unwilling to even get to parks and hiking trails and beaches. We’re all homebodies now, and yet the need for physical activity hasn’t diminished. If anything, it’s more crucial than ever that we stay active and healthy, fit and strong.

Today, we’re going to start with core workouts.

The core is, well, the core. It’s the foundation of your body. It’s how strength and force is transmitted to the world around you. It keeps you upright. And, although this might seem unimportant (it’s not), it’s a major component of LGN—looking good naked. Form and function depend heavily on the strength of your core.

You can do this entire workout in one block, sprinkle it throughout the day, or do some of it every day in addition to other training.

Primal At-Home Core Workout

Planks

This is the most basic core exercise. It’s simple (but not easy).

  1. Get in the pushup position, only put your forearms on the ground instead of your hands. Your elbows should line up directly underneath your shoulders. Toes on the ground.
  2. Squeeze your glutes and tighten your abdominals.
  3. Keep a neutral (straight, plank-like) neck and spine.
  4. Create a straight, strong line from head to toes—a plank, if you will.
  5. Hold that position for as long as you comfortably can. Stop short of failure.
  6. Rest for a minute and repeat twice more.

Make them easier:

  • By doing them on your hands rather than forearms (like at the top of a pushup).
  • By doing them on your knees; rest your knees on the floor or an exercise mat.

Make them harder:

  • Slide your elbows forward, so they no longer line up underneath your shoulders. This will increase the difficulty.
  • Add side planks. Hold a side plank on the left side for 30–60 seconds. Switch to the right side and hold for 30–60 seconds.

Toes to Bar

Here’s how to do it:

  1. Hang from an overhead horizontal bar, and touch your toes to the bar. Lift and lower in a slow and controlled manner for 3–5 reps.
  2. If you can’t do the toes to the bar, try just bringing your knees up to your elbows. Again, slow and controlled for 3–5 reps.
  3. If you can’t do the knees to elbows, try bringing your knees up to your chest. Slow and controlled for 5–10 reps.
  4. Do 3 sets, resting for 30 seconds between sets.

Check out the video here for an example.

Hollow Body Rocks

Here’s how you do it:

  1. Lie down on your back with your arms overhead and your legs straight out.
  2. Brace your core and lift your legs and arms slightly off the ground, creating a shallow U with your body.
  3. Start rocking back and forth while maintaining that solid shallow U position with your body.
  4. Rock for 20 seconds. Rest for one minute. Repeat twice.

Hands and Feet

hands and feet core exercise

There’s probably a better/more official name for this one, but it’s what I call it.

  1. Sit upright on the ground.
  2. Lift your feet off the floor.
  3. Touch your right hand to your left foot.
  4. Touch your left hand to your right foot.
  5. Keep going, never putting your feet on the ground.
  6. Do this for 20 seconds at a time. Rest for 40 seconds between sets; repeat four times.

Make it easier: Touch your hands to your knees.

Make it harder: Touch your elbows to your ankles.

There you go, that’s the workout. Once again, you can sprinkle these movements throughout the day or do them all in one fell swoop.

How are you training your core these days?

  1. Thank you. I don’t have a bar, but loved the workout. Thank you for your graciousness???

  2. Hey, can you sit down and touch your toes? Cool. Can you do a plank? Great! Now, can you lie on your back and lift both your arms and legs? That’s awesome.

    Now, I want you to hang from a bar and touch it with your feet.

    I mean, one of these things just doesn’t belong.

  3. Thanks Mark! It’s just a great reminder of how to spend a half hour listening to good music and feeling better.

    Be well

  4. Hollow body rocks are more fun to do if you pretend you’re a banana that’s rocking back and forth. We had to to them all the time in crossfit and the only way I could get through them is to say in my head “I”m a rockin’ banana!” That may just be me though. 🙂
    In related mind games, it’s much easier to do a row sprint if you imagine a crocodile chasing you behind your rowboat.

    1. Is the Rockin’ Banana going side-to-side, or r head-to-tailwhile it’s rocking? I can’t quite picture it.

      1. head to tail – good point – I should have mentioned that!

  5. I’m not quite understanding the last one. Maybe I’m just not flexible/strong enough to lift both outstretched legs off the floor at the same time?

    1. ditto! I just got on the ground and tried this. Barely came close.

  6. Another exercise worth mentioning is the sit-up. All you need is two metres of space to lie down in, and a sofa, chest of drawers or other article of furniture to stick your feet under. Lie with you legs straight, place your hands behind your head and pull yourself up. Your legs will bend as you do this but this is quite acceptable. A daily dozen to get your abdominal muscles in tone and keep them that way is very beneficial.

  7. Thanks Mark, good time to get these at-home workout suggestions. I do planks frequently, will have to ponder the rest of them, I find movements similar to what you are showing sometimes hurt my lower back.

  8. Thanks for this! Tried it today with my kids, now heading outside to get some walking in. We couldn’t make our bodies do the last one – any chance someone has a video of exactly how to do that? We couldn’t get both legs up at the same time – probably we are just too weak!
