interval core balance workout purely training #58

by purelytwins

We all need back-up plans, right?

Back-up plans are great to have in place as you never when you will need to use it.

For instance, we had another video planned but realized that the whole video did not get recorded. It happens. Luckily, we had another workout to use as our back-up.

Get ready to feel the burn in your whole body, especially your abs.

Interval core balance stability ball workout.

We love using our stability balls. They are great for adding more challenge to bodyweight workouts.  And you know we love our interval workouts too.

You only need yourself, a Gymboss Interval Timer and we recommend a stability ball if you have one. If not, no worries. In the video we go over what to do if you don’t.

Stability balls (or also known as exercise ball) can be a beneficial way to help improve muscle tone and balance.

Benefits of using a stability ball:

  • They can be used for low-impact aerobic exercise and strength training exercise routines.
  • May help to strengthen your abdominal muscles and lower back muscles.
  • Keep your stabilizer muscles more conditioned.
  • Strong core muscles also help maintain good posture.

Are you ready to have some fun with a stability ball? Good! We are too!

This workout is pregnancy safe for those in first trimester. If you are used to using a stability ball you can still use one in this workout. If you are not comfortable with stability ball we suggest following some of the modifications that Lori provides in the video.  Make sure to always listen to your body and don’t do anything that does not feel right when working out while pregnant.

We suggest:

B-fits (beginner peeps):  Take breaks when needed. Do an interval of 12 rounds instead of the 24. Omit using a stability ball if too much.

A-fits (advanced peeps): Push yourself in each interval. Use a stability ball as it adds more challenge to the workout.

FIT moms (pregnancy recommendations) : Go at a slower pace. Follow along with Lori. Depending on your fitness level do either 12 or 24 rounds. Take breaks when needed. Omit the stability ball if too much. Good for first trimester.

*disclaimer: make sure to consult with your doctor before trying anything new with your workout routine.
