You "could" do a half-hour of sit ups to work your abs...OR you could take a 45-minute strength or kickboxing class and strengthen your abs, back and obliques the fun way 🙃. We're all about functional core work! And we'll still throw in some sit ups for fun😉 #kickboxingstpaul #farrellsstpaul #farrellskickboxing #strengthtrainingstpaul
