I’ve had several friends ask me what I did and what they could do to get fit so I decided to nail down everything in this detailed article. I’ve also tried to bust a lot of ‘six pack myths’ in the process by backing them up with scientific explanations and relevant links wherever possible. Whether you’re fat, skinny or somewhere in the middle, I’m sure you’ll manage to takeaway something after reading this!
Bicycle: This exercise works your obliques as well as your rectus abdominis. Lie on your back, hips and knees bent at 90-degrees, chest curled over ribs, hands behind your head. Extend the left leg out while bringing the right knee in towards the chest and rotating the left shoulder toward the right knee. Keep the arm from crossing the face. Rotate from the trunk through the center to the other side without dropping your chest. Move in slow, controlled movements without shifting your hips.
Unless you are on steroids, training 4 times a week is the sweet spot for building muscle. You’ll need resting days for your muscles to grow. One day of training followed by one day of rest is the ideal set up for muscle growth but since there are 7 days in a week,  you can train either for 4 days or 3 days a week. Training for 3 days a week is too lazy for a lofty goal like getting six pack abs so it’s best to train 4 days a week and arrange your consecutive days of training to target different muscle groups in your body. Sure, some muscle groups will inevitably be trained for 2 days in a row but that’s a minor issue when you consider that you have 3 whole days of resting in a single week.
The Torso Track comes out as number 5 for effective ab exercises, but this is one of my least favorite exercises because it can cause lower-back pain, particularly if you roll out too far. In fact, in the ACE study, researchers found that a significant number of subjects reported lower-back pain, so you may want to skip the expense, and discomfort, of this one and choose other exercises that can target the abs with equal effectiveness.
“For me, getting a six-pack was about paying attention to what I was eating and lifting heavy weights at CrossFit. I do have a semi-strict diet, and I loosely count macros (focusing on daily carbs, protein, and fat intake rather than blindly counting calories) to stay balanced and on track. It sounds like a lot of work, but it really isn’t. Eventually, it just became a part of my lifestyle, and it’s something I enjoy doing. I even started a custom meal-plan business based on macros because I had such great results!” —Tina Haupert, @carrotsncake
