Get a core workout done fast with this STEADY core engagement. Make each move count while you steadily engage your abs for the next 8 minutes. A couple different variations on the crunch will fire up the whole 6 pack. Try not to laugh while doing “Halloween coffins” too. Or if you do, at least it will be a bonus ab-tightener. The steady work through these 8 minutes will leave you sore tomorrow, but you got this! No shoes required. It’s a great one to tack onto the end of a run before you cool down with a stretch.
