Summer may be half over, but the Tone It Up Girls - Manhattan Beach, California-based fitness trainers Katrina Hodgson and Karena Dawn - say there's still time to get into shape for the beach or pool.
Here are four simple exercises the girls use to keep their bodies toned and bikini-ready - and that you can use to similar effect.

Dead-Lift Crunch: Starting Position
Hold a dumbbell in each hand, and stand with your feet shoulder-width apart. Bend over and roll the dumbbells down your legs. Keep your back straight and squeeze your butt as you inhale.
Dead-Lift Crunch: End Position
Exhale as you return to an upright position, performing a bicep curl and lifting your left knee toward your waist as you turn to the side to perform a crunch. Repeat three times, alternating sides.
The Dead-Lift Crunch tones the core, biceps, and the backs of the legs.
Girdle Lunge: Starting Position
Holding a dumbbell with both hands, stand with your feet shoulder-width apart.
Girdle Lunge: End Position
Step backward with your right foot, and inhale as you trace a figure eight over your left leg. Exhale as you return to the starting position. Repeat three times, alternating sides.
The Girdle Lunge tones the thighs, butt, abs, and waistline.
Booty Blaster: Starting Position
Wrap a "mini band" around your ankles, keeping your feet shoulder-width apart.
Booty Blaster: End Position
Keeping your abs tight, bend your knees slightly and step to the left five times. Then step to the right five times, being careful to keep your abs tight and knees slightly bent. Repeat three times.
The "Booty Blaster" tones the outer thighs and builds knee stability.
Tummy Tuck: Starting Position
Begin in the plank (push-up) position. Be sure to position your shoulders directly over your wrists.
Tummy Tuck: Finishing Position
Touch your right knee to your right elbow. Return to the plank position, and then touch your left knee to your left elbow. Repeat three times.
The "Tummy Tuck" sculpts the shoulders and tones the abs, obliques, and outer thighs.
"We encourage people to get into shape with workouts that are fun instead of torturous," says Katrina. ""Most people think of fitness as something you do in the gym. But fitness is a lifestyle."
