This Core Challenge Builds Mobility, Stability In Your Home

The four-week challenge works your core without equipment

During the pandemic, keeping – or getting – or core (belly and back) in good shape is relatively easy to do and requires no equipment.

I offer the Fit From Home Challenge, just to challenge ourselves, do something together, and keep fit during social distancing.

The Fit at Home Challenge is mostly a back and core workout from home with pushups and some kind of leg work to boot. So it increases your core mobility and strength.

Here are the guidelines:

  • Do the Challenge five days of the week.
  • You have ALL DAY to complete the workout. That means you can break the work into halves or even quarters to build up your strength.
  • If this is too easy, you can add 10 reps or 30 seconds on to all the exercises!

The exercises for a solid core workout from home

The Fit at Home Challenge is a back and core workout from home with pushups and leg work that increase your core stability and strength.
One of the leg exercise options is the Bulgarian Split Squat. Great for building strength and balance!


Leg work. Choose One of the Following:

Air Squat: Hold your hands at your chest while you sit back in a squat with your weight on your heels. Make sure your knees are roughly over your shoelaces.

Split Squat: Bring one leg forward into a split stance. Keep your torso upright, hands at your chest. Drop your back knee straight down so your front knee is roughly over your shoelace. Do all the reps on one side first. Try to bring the back knee to the ground, but modify as necessary.

Bulgarian Split Squat: Similar to Split Squat, but the back foot is elevated on a bench or low object like an ottoman. Remember to keep your front knee is over your shoelace. 


You may do these on your elbows or hands. Keep your belly tight and pulled toward your spine. If you need to modify, use your knees. Try to keep your knees elevated and build toward the full time throughout the day! 


Lie on your back. Raise your arms overhead with your hands on the ground. Press the small of your back into the floor, squeezing your abs tightly. Then, raise your feet and knees off the ground. Straighten your legs and extend them just off the floor. Raise your torso off the ground so that ONLY the hollow of your back is on the ground. Hold!

Russian Twist

Hold a heavy book or laundry detergent bottle or gallon of milk in your hands while you sit on the ground. Raise your knees up with your feet still on the ground. Lean back slightly. Tap the weight on either side of your, twisting your torso. Move slowly and deliberately. Then, straighten legs and do rotations. Then, lean back further closer to the ground. 

Super Hero

Lie on belly. Raise arms off the ground and hold. Then, raise legs off the ground and hold both arms and legs. Then, squeeze belly down into floor. With your arms overhead, shape them into I, then a little wider into a Y, then a little wider into a T, then a W with elbows down and back and hands up. Each movement should tightly squeeze the shoulder and back muscles.
