Regarding relaxation, I’ve found the following methods to be valuable:
- longer sprints out to 60yds
- flying sprints out to 80yds (20yd pre run)
- set intensity limits at 20-30yd and continue out to 50-70
- also using a sled with intensity limits
- intensive tempo
- longer extensive tempo (+160yds)
- and the equivalent, believe it or not, of special endurance (although this is by no means a regular event)
Regarding the special endurance run (ergo +200yd) I’ve found that the players will naturally ease into a relaxed upright position. Again, this is nowhere near a regular event; however, when I’ve thrown it in it has proven to yield a pleasant surprise- technically.
