In her third Women’s Running-exclusive Diet Bet Challenge video, former cover runner Karina Smirnoff demonstrates a quick leg drill that can be done on a curb or step in your house. She recommends 5 sets of 8 counts per move, but we say start with however many sets and/or counts that are doable for you—and go slow if need! This type of workout will help leg turnover, agility and strength, especially for trail runners. Tune in next week for Smirnoff’s fourth video, and follow or join her entire #LoseWithKarina challenge at the DietBet website.
