If you've been doing the same strength-training exercises for months, your muscles may be in a holding pattern.
TWEAK: ADD LEG SWING
Holding a plank position (resting your weight on your forearms and toes, with abs pulled in), lift your right toes off the ground and swing your right leg to the side, toward your hips. Return to the start position and perform on the other side. Do 15 reps on each leg; rest and repeat twice.
TWEAK: ADD ARM SWING
Stand with arms out in front of you. Extend your right leg in front of you and slowly lower yourself into a squat position. Pause, then slowly push yourself up to standing. Do this exercise in front of a mirror, checking that your knee doesn't turn inward. Do 15 reps and switch legs. Do three sets of 15 reps on each leg.
TWEAK: LIFT ONE LEG
Lunge forward with your left leg. Swinging your arms, jump up and switch legs to land in a right lunge. Jump and return to the left-leg-forward lunge. Do three sets of 15 reps.

3. No Sweat While sweat isn't the most accurate indicator of an effective work-out, if you're walking away with dry pits and forehead, "it's time to advance your routine."
