This is a no excuses exercise because all you need is YOU to get it done!
The first variation, I walk my feet back to the plank. If this is new to you, or you have issues with your back, I'd go for that one. The next progression, I jump my feet back. As long as your hips stay at shoulder level and don't drop below, your back will be fine. Just be sure your hips don't go above shoulder level because that could create a lot of tension in your neck.
Try incorporating this into a HIIT circuit or performing the movement for 20-60 second intervals with 10-30 seconds of rest in between sets. Share when you incorporate this into your core workout on Instagram/Twitter @cassiebstrong #BStrong!
