Do you lose track of where you are in your workout? Or have to keep staring at a clock on the wall? And you don't have the patience to play with some fancy app with all the features you'll never use. Focus on the workout, and let TimedTrainer handle notifying you when to move onto the next exercise. Even while it's locked, and while you're playing music, TimedTrainer lets you track your Crossfit, HIT, or Tabata workouts. TimedTrainer is designed specifically to create your workout in just a few seconds, so you don't waste your time fiddling around with your phone instead. There are no frills, and the idea is very simple and flexible for all your workout needs. 1. You create a new workout, and add intervals/rounds. 2. Each round has a duration and an optional rest period. 3. You can have unlimited rounds in a workout, and then repeat/loop it unlimited number of times. For example, today I feel bloated, so I want to work on my core. How about I create a "Bloat Buster" workout that has: - A minute of crunches - 30 second plank, rest for 5 seconds cause planks hurt! - A minute of bicycle kicks Let's repeat that 5 times, and go! Swift, Sleek, and Smooth, that’s what we are aiming for, and I bet you are too. TimedTrainer is great for: Boxing High Intensity Interval Training (HIIT) Crossfit Tabata Circuit Weight Lifting Stretching Martial arts drills Jogging Wrestling Fartlek
