Tired of the basic interval workouts you've been doing over and over again? Forget about speed intervals. This treadmill hill workout incorporates one-minute butt-lifting moves to bust through your cardio-machine boredom. Talk about a major butt and thigh burn!
|Time||Speed||Incline||Leg work — off the treadmill|
|10:00-11:00||Alternating front lunges|
|22:00-23:00||Alternating reverse lunges|
Be careful getting on and off the treadmill, as it will still be moving. Also, this workout is not one that would work well in a crowded gym, especially if there are people waiting to use the machines. If this is too hard or too easy, adjust the incline and/or speed to fit your level. Don't forget to print this workout — your jeans will thank you!
