"I always start every workout with 15–20 minutes of abs and stretching. I don’t feel like I can begin my workout unless my #abs are warmed up. Doing this reminds me to keep my abs tight throughout the rest of my workout and throughout the rest of the day. People don’t realize that they use abs in almost every exercise, so you need to keep this area tight to maximize your effort when hitting other areas." #Crunch 4x30
