Think celery is the only thing that should crunch? Are sit-ups your exercise equivalent of a root canal? Good news: You can achieve firm, flat, sexy abs without doing either. “Strength moves requiring balance work the tough-to-reach
transversus abdominis more effectively than traditional ab toners do,” says Robert Sherman, a trainer in Rockville, Maryland, who designed this sneaky sculpting routine. You’ll need anything that creates an unstable surface: folded bath towels, a BOSU or a pair of balance pods. Complete two sets of each move up to three times a week on alternate days, and you’ll be ab fab in a flash!
弓步
左脚踩在豆荚上，下到弓步，膝盖在踝关节上，大腿平行于地面，右膝盖弯曲，抬起臀部，手在臀部上（如图所示）。当您伸直左腿时，将右脚的球推开，将右大腿放在前面并平行于地面，在豆荚上平衡。慢慢返回开始。做12次。开关腿；重复。
Get-lean lift
站在臀部宽度的脚上，右脚吊舱，武器向下。当您接合ABS时，将手臂抬高到肩膀的侧面，然后尽可能地将左腿延伸到侧面（如图所示）。慢慢返回开始。做12次。开关侧；重复。
Power plank
Start in plank position, forearms resting on pods (spiky side down), hips lifted, legs behind you, resting on toes (as shown). Hold pose as long as you can; work up to 60 seconds. Lower to knees; repeat twice.
Shaky squat
Stand on pods with feet hip-width apart, knees soft, arms down. Engage abs and raise arms to shoulder level for balance as you slowly squat as low as you can (as shown). Return to start. Do 12 reps.
Tree 2.0
Stand with right foot on pod, sole of left foot pressed inside left shin, knee out, and palms pressed in front of chest. Engage abs and hold pose. If you can, slowly extend arms overhead (as shown), then lower. Hold up to 30 seconds as you maintain balance. Switch sides; repeat.
涡轮扭曲
Start in push-up position, with ball of left foot on pod and right leg raised in line with hips. Engage abs, bringing right knee toward left armpit (as shown). Return to start. Do 12 reps. Switch sides; repeat.
The gymnast
坐着腿伸开，脚跟在豆荚上，手腕直接在肩膀下方，手掌平放在地面上，手指向前指着。将臀部从地面上抬起。当您接合ABS并尽可能高（如图所示）时，保持臀部升力。慢慢返回开始。在另一侧重复一次。做12次。
