4 Simple Exercises to Get a Flat Belly in 4 Weeks

A lean, sexy tummy is something most of us want. Unfortunately, you can’t just exercise your way to it. A lot of it has to do with what you put in your mouth.

Your core is the center of your body. You need to identify it, engage it, and let all movement emanate from it. It’s also important to go beyond basic crunches. They’re one-dimensional, hitting only the rectus abdominis (or six-pack).

My Quickie series targets the midsection from multiple angles, which is part of the reason my clients over 40, like J.Lo, still have chiseled abs. Pair them with 30 to 60 minutes of cardio, and aim to do them six times a week.

Exercise 1

Hiit workout

Begin in plank, tucking right knee into chest. Rotate waist so outside of right hip and thigh are facing floor. Lower body to sit on right hip (A). Raise body to plank, then raise and extend right leg (B). Return to starting position. Repeat 30 to 40 repetitions on opposite side.

Exercise 2

Hiit workout

Lie face up with legs together and straight out. Rotate hips slightly to left so legs are on left diagonal. Place left hand lightly on back of head and extend right arm straight out to side, palm facing down (A). Crunch up and raise legs, keeping legs on diagonal (B). Slowly return back to floor. Do 30 to 40 repetitions; repeat on opposite side.

Exercise 3

Hiit workout

Lie face up with legs wide apart, toes pointing up and hands resting lightly on back of head (A). Extend right leg, letting toe point outward, and raise leg (B), using inner thigh to lower leg and return to starting position. Do 30 to 40 repetitions; repeat on opposite side.

Exercise 4

Hiit workout

Lie face up with legs together and straight out. Place right hand lightly on back of head and extend left arm straight back over head holding 3-pound weight (A). Raise legs to 90 degrees and squeeze upper and lower body as left arm is raised and then lowered forward until it’s in line with torso (B). Return to starting position. Do 30 to 40 repetitions; repeat on opposite side. Keep neck neutral so you don’t strain it.
