Here's a new twist on a classic LT interval workout. Each 3 minute rep starts out at LT (Lactate Threshold) pace for the first 2 minutes and then you bump it up twice over the last minute to 'kick' it in. In running a 'kick' is when you finish a race fast by sprinting to the finish line, it's also sometimes called a 'finishing kick'. Each successive rep challenges you to 'kick' it in a bit faster than the last one. Finish all four and you will be well on your way to honing that final sprint to the finish line.
