Since push-ups are done in a plank position, and proper core engagement is essential in order to complete just 1 push-up, I 100% count them as a core exercise. Throw the BOSU in the mix to challenge your shoulder stability and kick your core into higher gear, and now you're talking high intensity!
In the video, I put my foot flat on the floor when I bring my knee forward. I do this for a couple reasons. 1. Lifting a foot off the floor is going to make you way less stable when your hands already feel very unstable on the BOSU. If it's your first time doing this, putting your foot down may save you from face planting onto the BOSU. You're welcome. 2. By making the knee tuck a lunge, I work my core as I pull my leg forward and then open up my hips as I lunge, which feels amazing when my lower back feels tight. If your hips are feeling wonderful and you're a beast at this exercise, then just pull your knee forward and keep your foot elevated so that you're really relying on your core to keep you stable!
Try 10-20 reps, (determine this by the number of push-ups you can do), for 2-4 sets.
