punishing cardio

[MADLaxD7]

Hey all FNG here,

just wanted to know if any of you have a punishing cardio workout to regain speed and agility other than sprints. if you could help me out I would definitely appreciate it.

run hills, suicides (sprints like 1, 3, 5, 7, 5, 3, 1) cone drills..theres like 20 cone drills u can do..get creative...do a mile run sprinting the straights and jogging the curves of a track...

if u hav like a lax field or soccer field near u, doing full field suicides and high knees and butt kicks etc. will help u get into good shape. also running up and down stairs is great cardio as well as jump rope
