My dad and I tested out this watch and let me tell you — it's INTENSE. I workout regularly and this bad boy will definitely keep me in check going forward. It syncs up to an app on your phone that provides you with very detailed statistics on your cardio load, muscle load, and more. It has TONS of workouts you can track ranging from an outdoor walk and golfing to indoor cycling and long distance running. If you're looking to take your workouts to the next level, this will be quickly become part of your routine.
Promising review: "As an avid trail and road runner (running 80-100 mi/week), I cannot review this watch highly enough. Having trained in a variety of watches over the years this watch is by far the best. The battery lasts forever before recharge, it is easy to figure out how to use, and it has all of the relevant features (HR, current pace, average pace, POWER!!!, splits, elevation, etc). As a trail runner, the new power metric has been extremely valuable since it is the only metric that remains constant through hills (HR goes up, pace goes down, power stays the same). Moreover, the watch is comfortable enough to sleep in, and is sleek enough to wear to work in a professional environment! I really have no critiques at this point and would recommend to anyone looking for a performance-oriented, good-looking, comfortable watch." —Amazon Customer
