big_lex_the_racer: Gotta put in the work...! This workout is really good for the legs and getting the heart rate up. Dragging the #sled on a soft high friction surface simulates that #ocr #hillclimb. Weighted #lunges also really helps out on those hills while surprisingly works the #shoulders. Practicing the #sandbagcarry on the max incline is a must for #spartantraining. And the #sandbag hops are great to keep the #heartrate up. And of course the #trainingmask kicks it up a notch. #lovethepain #toughmudder #battlefrog #racingnoob
