The best workouts are usually those that include interval training. If you'd like one that will always keep your body guessing, or you're a trainer trying to do the same, use this tool to create random timing for each exercise. For those with less passion for fitness, this is also a great way to set timeout lengths for your misbehaved kids (we think that should create some fear of repercussions). It's also great for setting a schedule, so let this tool decide what time you should do what you need to do.
You can also generate a random date.
