Today, I want you to give me the most perfect push ups you have ever performed. We have been doing a lot of work on our core and stabilizers, not to mention our upper body strength, so let's put that all to work for us. Push ups and any plank variations are such super moves as they not only build strength but help with balance and flexibility as well, while boosting metabolism to boot! Activate both your core and your glutes as you move to keep that spine neutral!
