300 Workout Question

[TUEFELHUNDEN]

Sorry if this sounds stupid but would it be worthwhile to try mixing in the 300 workout into my lifting? I am trying to improve my fitness for racing MX and in the past I have stuck with circuit style weight lifting and jogging/biking but this year I want to keep my focus on getting stronger and keeping in good cardiovascular shape.

Right now I am using a modified 4 day (M,Tu, Th, F) program from intense workouts.com and I have been doing HIIT running on off days along with biking in 15 minute segments. My races are only 15 mins. long give-or-take so I don't have to go overboard with the conditioning.

Sorry if this is a newbie question but I have "searched" and haven't really found a good answer. Any other suggestions would be appreciated.

Thanks,
Randall

Do you mean the entire program that the guys from 300 went through or just the "300 workout" that they took as a test at the end of the program?

I meant the workout that they show on Men's Health. Thanks for the info on CrossFit.
