P90X Day 65 Ploy metrics Since I am hoping to get right into marathon training at the end of my 90 days I figure I need to start incorporating more running into my P90X, so I came up with what I'm calling my Plyo-Run workout. Here's how it goes: 1 mile warm up 5 x 400 m on track with 30 second plyometric jumps between each 400. Then a 400 m recovery walk after the fifth repeat. Repeat 3 times My original intent was to run the 400s at 1/2 mp (1:35), but that didn't last long. Looks like I should shoot more for mp (1:42). Doing those plyometric jumps is killer. I picked 12 of the jumps from the workout: squat reach jumps, run stance squat jumps, jump knee tucks, Mary Katherine's, leap frog squats, twist jump combos, lateral leap frog hops, monster truck tires, hot foot, squat jacks, jump shot, and football hero. This is a killer workout. Total distance 5.5 miles |
