Flutter kicks- sounds dainty but burn like no other! Keep that low back on the ground and hold on to something positive!
Start lying on your back. If you have a weak core or lower back, feel free to put your hands underneath your hip bones for support and to create the correct pelvic tilt. Using your core, you are going to lift you feet about two feet off the ground. Then flutter your feet back and forth in about a 12 in range of motion. Keep your core tight and use your breathing to focus on good core contraction.
I recommend several short bursts of this movement to focus on form while you exhaust your core and find a good burn.
Stick around for Day 9: Over-Unders ! Feel free to comment with any questions or concerns or email me at firstname.lastname@example.org
