Interval Sprints! Any suggestions?

[Phenomkidd]

I've now started doing sprints as part of my training regime. I'm basically jogging for half a mile then I do 8 x 100 metre sprints. I'm hoping to build this up over the next few weeks. Anyone got any suggestions for other types of interval sprints? It would especially help to hear any routines from any fellow super heavyweights out there! Cheers.

[_LOAD_THE_LEFT_]

50 yd. spint x 20, 100 yd. sprint x 10. 30 to 60 seconds rest in between.

sprint 2 or 3 min. 3 times at least with 30 to 60 seconds rest in between. hard at first but youll get better in time.
