Produced by Troy Jacobson's video production company, LifeSports, Inc., 10k Strength Builder is a 50 minute treadmill workout designed to improve your anaerobic threshold, strength and sense of pacing.

The workout, set to upbeat music which can be turned on or off, starts with a 10 minute warmup at a comfortable "base pace". Midway through the warmup Coach Troy throws in several 30 second "striders" at 2mph above base pace and a 2% incline. The striders are simply designed to elevate your heart rate and prepare your legs for the impending 5×6 minute repeats. Click HERE for the complete review.
