Basically, you will be building a better you, and with this circuit-style workout, you will do it faster than you could imagine. BEAT-SYNC Boot Camp Challenge dynamically changes the beat of YOUR music to perfectly match your movements. Research shows that music distracts the brain during exercise and faster music causes people to accept and even prefer a greater degree of effort. This means you will work harder without trying (or without even feeling the difference), you will get better results from the increased effort, and most importantly, the time will fly by. DESIGNED AROUND YOU Lori Patterson has worked with thousands of people and she knows how to safely and effectively guide anyone towards their goal.

Change the exercises to match your equipment or simply pick your favorites. You can even turn the intensity down a bit when you're struggling or crank it up when you're ready for more, and Boot Camp Challenge adjusts your workout — and your music — on the fly.
