Building up that core? According to a study by the American Council on Exercise (ACE), bicycle crunches are one of the top three exercises for strengthening your abs.

 

This month, join us for a daily session of bicycle crunches – a workout you can do anywhere! By the end of this 30-day challenge, you’ll be bicycle crunching your way to defined abs that’ll power you through anything. This challenge builds slowly day by day, so your strength and endurance will enable you to easily complete all the crunches listed for the final day. If you’re a bicycle crunch beast, feel free to double up and multiply each day by two.
