What is Murph challenge?
Murph challenge is named after Navy Lieutenant Michael Murphy, who was killed in Afghanistan in June 2005 at the young age of 29. The workout comprises one mile run, 100 pull ups, 200 push ups, 300 squats and one mile run. One needs to wear a weighted vest of about 9 kgs while doing this challenge; women need to wear 6.35 kgs of vest for this.
"This year I got it done in 39:58"
In June, Mark Zuckerberg posted about completing this challenge. "I try to do the Murph challenge with the girls every Memorial Day as a tradition to honor those who defended us. One of Lt Murphy's favorite workouts was running a mile, then doing 100 pull ups, 200 push ups, 300 squats, and then running another mile -- all while wearing a 20lb weighted pack. This year I got it done in 39:58. The girls did a quarter-Murph (unweighted) in 15 mins!," he had posted on Facebook.
Murph challenge is tough
It is difficult to do the Murph challenge, as it works on the major muscle groups of the back, the shoulder, the chest, the legs and the torso. The weight of the vest and the cardio run also add up the intensity and degree of the workout.
Murph challenge increases heartbeats by 11 beats
As per a study titled "Weighted vests in CrossFit increase physiological stress during walking and running without changes in spatiotemporal gait parameters," running and the additional weight of the vest increases the heartbeat by 11 beats per minute. This increases the amount of oxygen we consume and increases the amount of calories that can be burned.
