This is by far the best piece of kit I've ever bought for my training! (If you've been to Bootcamp you'll be familiar with it!)
I would say this will be the best investment you could make in your training! Couldn't recommend it enough!
You can use it for timing your rest periods, timed sets and intervals, circuit training, timed workouts and just about anything else! Get one!
