How to do it: Grab the kettlebell in one hand and stand at one end of the room. Draw shoulders down and back, lift chest, and engage your core. Maintaining this muscle engagement, begin to walk forward while holding the kettlebell in one hand. Continue walking for 20 steps, and then switch hands and repeat.
Be sure to walk with proper posture and do not take wide strides. Do 1 set of 20 steps each way.
