Since I definitely didn’t get up at any reasonable time to be able to run this morning I just went in at noon and pulled the sled with 100 pounds for 15 minutes in roughly three minute bouts. Then I did 30 reps in each direction of neck work with 25 pounds.
I think this easy sled pulling is doing it’s job as far as better stamina, more lower body strength and faster recovery is concerned but I’m really not sure. I’d be really interested to know what the metabolic cost of this drill is and if it’s comparable to “normal” cardio-type activities. My subjective evaluation would say it’s probably on par with a strenuous walk or an easy jog.
