To share a bit of the Tone It Up 21 Fall Challenge, Karena and Katrina from TIU put together this powerful full-body, strength-training workout that they say "will sculpt your gorgeous bod from head to toe — arms, abs, booty, everything!" The two trainers say they love full-body workouts "because they help you form lean muscle while boosting your metabolism."
The following five moves are a sneak peek into the Fall challenge and will focus on using drop sets of weights, which means you start using a heavier pair of dumbbells and drop down to a lighter pair in the middle of your set. "Drop sets help you strengthen your muscles and perfect your form while working up to heavier weights," the trainers told POPSUGAR. "Perform 21 reps of each move" and the whole circuit three times through, using a heavy pair of dumbbells for the first seven reps, medium dumbbells for the second seven reps, then either light or no dumbbells for the final reps.
