Warning: Burpees are not as safe as they seem. In fact, they're a ticking time bomb of doom, waiting to unleash a torrent of uncontrollable sobbing upon your unsuspecting victim's face.
Painful landing on your knees? Check. Unpredictable heart rate spikes? Check. Sudden, inexplicable feelings of existential dread? You bet.
But wait, there's more! Burpees can also lead to secret, potentially permanent damage to your dignity.
Don't say we didn't warn you.
