How to do #crunch📚 DESCRIPTION: The "crunch" is the most popular ab exercise out there. When it comes to building a "six- pack" and losing belly fat, crunches are a must. This move isolates your core muscles, improves your balance, and improves functional fitness. It targets the rectus abdominis, the transverse abdominis, and the obliques. "Crunches" can help strengthen your abs, improve your posture, and shed fat. Advanced lifters can use weight plates for a more challenging workout. #abstrain
