Darebee is absolutely fantastic, and has been for years. They used to publish these one-sheet-workouts under the name of their founder Neila Rey and they have always been concise, ad free and low barrier of entry. They have been free the entire time, so I only recommend donating to them. They also published two Android apps which are absolutely worth checking out:
"Workouts by Darebee", which presents you a random workout sheet (multiple workouts with repetitions and a timer) and
"FitTap by Darebee", on which you are shown a random single workout. Tap anywhere on the screen for the next random workout.
I really cannot recommend them enough, they set the barrier of entry so incredibly low it's fantastic. I used to tediously plan my workouts, order, number of sets, read up on them in the web etc to exhaustion that I almost forgot to actually start the workout. That of course also has it's merits, but for a very quick 15 minute workout in your lunch break, these apps are so much better.
