Bar Rafaeli

While models are used to looking their best in public, Bar Rafaeli isn't afraid to let the world see her perspire. During one of her recent hour-long workouts, the model uploaded pictures of herself looking sweaty and worn out after jumping rope, completing a set of lunges and doing plank exercises. "Gooood morning! This is how I start my day... The smile doesn't last for long," she tweeted. Rafaeli grinned and goofed around while snapping pics in the gym to share with her fans on Twitter. So take a lesson from her: No matter how hard the workout, try to have a bit of fun. Add some tech to your training by snapping pictures of yourself and uploading them to Facebook or Twitter. Your friends will comment and cheer you on, while the mini-breaks will keep you energized.
