THE PLANK Works all abdominal muscles, lower back, shoulders, glutesKneel on the floor. Bend elbows and place forearms on ground, clasping hands and forming a small triangle with hands and elbows. Straighten legs and
balance on forearms and toes, feet six inches apart. Once balanced, make sure tush is level with the rest of body, forming a straight line from the
top of your head to heels (as shown). Keep abs engaged to prevent back from
sagging. Hold for six counts, building up to 30 counts (counts sound like
“1-1000, 2-1000, 3-1000”). If this is too challenging, keep your knees on the ground and shift forward so you¿re balancing your weight just above your knees.
CRISSCROSS Works abs, obliques, quads
On back, clasp hands behind head and slightly lift the tops of your shoulder blades off floor. Straighten and lift left leg a foot off the floor as you twist at waist, bringing right knee slowly in toward left shoulder (as shown). Be careful not to round your back or pull on your head or neck. Hold for two counts, then twist to the other side for one rep. Aim for 8 to 12 reps.
STANDING CHOP Works waist, obliques, lower back, glutes, legs
Stand with feet hip-width apart. Extend left arm overhead, right hand resting on hip (as shown). Keeping core engaged for balance and left knee soft,
bring right knee up and pull left arm down in a controlled chopping motion, aiming for the outside of the knee with your elbow, for one count.
Return to start for two counts; aim for 8 to 12 reps on each side. For an extra challenge, hold a two-pound weight in the “chopping” hand. Note: If
you can’t reach your elbow all the way to your knee, simply go as far as feels comfortable.
THE AXE Works obliques, lower and mid back, shoulders
Standing with feet slightly wider than hip-distance apart and holding a one- to two-pound weight in each hand, bring both hands over left shoulder. Exhale as you chop down with a slow, controlled twisting motion toward right leg, keeping both feet planted on floor. Slowly,
using your abs, not momentum, to control speed, return to start. Do 8 to 12 reps on each side. Women with back problems should be especially careful
not to over-rotate.
THE SWIM Works core, lower back, shoulders, glutes, quads
Lie facedown, arms extended overhead, palms facing down. Lift head slightly off the floor, tilting chin down to form a straight line with neck. Tighten abs to create a space between your belly button and the floor. Raise right arm and left leg one inch off the floor (as shown). Do not try to
go higher. Hold for one count, then lower. Repeat on other side, completing 8 to 12 reps on each side. Beginners can rest between sides, lowering head, arms, and legs to the floor; as you progress, you may remain slightly elevated the entire time, as if swimming.
