Set up standing with two dumbbells weight plates, or other relatively light alternates. With core knitted down, raise your arms to an I (forward), Y (45* out), and a T (to the sides). If indicated, also raise your elbows, then pivot upward to a "goalpost" shape, then press overhead and return through the "goalpost" as shown in the later part of the demo. Start with light weights for this exercise, especially if you're including the "goalpost"!
