Triple Threat launches with a unique lower-body muscle-building workout that you'll want to keep in your back pocket moving forward. But for now, just survive this leg day! Your Triple Threat adventure starts with a single command: squat! But you can forget your comfortable three sets of 10 for now. Just put your bodyweight on the bar, set a timer or eyeball the clock, and push it for 30 seconds straight! If you've never squatted for time, prepare for a challenge! Depending on how heavy you normally squat, you might just get a few reps, or plenty. You don't have to count. Just squat! If you don't have raised-heel squat shoes, consider sticking some 2.5-pound plates beneath your heels. This can help you keep your form intact as the fatigue builds. If your gym doesn't have a glute-ham developer, feel free to use a 45-degree back extension bench instead for the last movement. Now go to town! Shop RSP Supplements ► http://bbcom.me/2cRMO0y
