From a downward dog position, plank is great for strengthening the whole body it utilizes a push up position. But were going to add a balance challenge of extending opposite arm and opposite leg while, holding plank pose. Were going to put our hands right underneath our shoulders, and these are going to be hip with a part, your going to curl your naval towards your spine to support a nice active core, curl your toes and, were going to release and extend that and balance and distribute that weight nice and even. From here were going to activate, and release one foot one arm, and down, inhale, exhale, and release opposite way, activate that center of gravity, and hold, hold plank position, drop your knees and release back into neutral. Again, make sure you master your bilateral movement of plank before you move into extension of one arm and one leg. Always have an active core, and you can always try by holding one, knee down and extending out so you have more of a stable base. And then you can curl your toes, come up, and hold, and create the balance challenge that way. So, always build your foundation first before you move into the advance movement of one arm one legged plank.
