Author: Bebetterrunner

Get back in shape, work-it-out your self using the high intensity interval training (HIIT) principles.
- no more excuse, do it anywhere, inside your home, or on the go
- just need your watch.... no fancy gym equipment
- customize it to fit your own needs.
.
HOW IT WORKS?
 - You will do "rounds" of different workout types & alternate between intense bursts of activity and fixed periods of rest recovery. Example: spend 45 seconds doing a workout like "jumping jack", then rest for 15 seconds, then go to the next workout, like "push ups", then rest then the next one...
- a timer on bottom shows you time left in current workout, total time left
- a white indicator runs around the watch each "workout-rest period". The "red" zone is 45 sec exercise time (configurable), "green" zone, 15 seconds recovery time (configurable).
- an inside progress white arc will show you the % of total time of the whole workout, all rounds of workout added.
- after a round of workout, the next round will start from top of workout list. Imagine you are in a room and "stop" by each corner for a workout. When you do the full room round, you start again with the first workout. 
- when finished, hit the "enter/start/stop" button and select either to resume the activity or save.
- if the heart sensor is enabled, a scrolling graphics will show your heart effort trending as you exercise
- if you do not know how to do a specific exercise, look it up on the internet. They are tons of great sites / youtube to explain to you how to do them best.
.
WHAT CAN YOU CONFIGURE? To configure, see https://apps.garmin.com/settingsHelp I personally prefer the Garmin Connect mobile app for my settings. 
- number of rounds of workout
- type of exercise for each workout, write your own if you wish
- duration in seconds for each workout exercise (30 seconds to 600) /rest (5 sec to 240)
- opt in/out for activity recording, sound/vibration notification
