7 tips for sharp abs
Weve given you more than a few solid ab routines to help get your midsection looking sharp over the years. Now, here are seven tips to make sure you don’t inadvertently become your abs worst enemy:
1) Don’t eat fast-digesting carbohydrates. Fast carbs spike insulin, which halts fat-burning and boosts fat storage, particularly on top of your abs. Carbs to avoid are white bread, white potatoes, regular sodas, sports drinks, table sugar, etc. Instead, choose whole-wheat, rye or sourdough breads, oatmeal, sweet potatoes, fruits, vegetables, quinoa, legumes and brown rice. One exception here: You can eat fast-digesting carbs right after workouts when they’ll be put to work boosting muscle recovery and growth.
2) Don’t neglect isometrics. More formally known as the Weider Iso-Tension Principle, this means flexing a bodypart, such as the abs, and holding that position (much like bodybuilders do when posing). To do this, tense each muscle for 6–10 seconds, then relax for 6–10 seconds. Repeat for 10–20 sets. This is a great way to hit your abs while sitting in your car, on your couch or at your desk.
3) Don’t forget about your breathing. When you perform an ab exercise such as the crunch, exhale when you reach the finish or top position. This is important because it helps you better contract your abs. Holding the position for a second or two will maximize muscle-fiber involvement.
4) Don’t stop. You typically train in specific rep ranges, such as 8–10 or 12–15 reps per set. Yet when doing bodyweight ab exercises, you can’t alter the weight to match a predetermined number of reps. Therefore, rather than doing crunches or hanging leg raises for a set number of reps, do as many reps as possible until you come close to failure.
5) Don’t forget to weight. Many guys worry that if they do weighted ab exercises, their abs will become thick and blocky. Yet abs are muscles just like biceps, so they need definition
and separation to stand out. Do some weighted movements in the 8–10-rep range for optimal ab development.
6) Don’t do abs first. Some trainers recommend that you begin your workout with ab training to make sure you don’t skip it. We disagree.
A recent study by the Weider Research Group found that when trained lifters did abs before legs in a squat workout, they completed fewer reps of squats than when they trained abs after the squat workout. This is because the abs, obliques and transverse abdominis work together to stabilize the core, which allows you to produce greater force. Training abs first fatigues them, which lessens your core stability and weakens your base, as well as your ability to generate force.
7) Don’t train abs always at the same speed. Regular readers are well aware that m&f recommends changing up your rep speed from slow and controlled to fast and explosive, allowing you to utilize more fast-twitch muscle fibers to build more power, strength and size.
According to new research from Spain, scientists tested the muscle activity of subjects’ rectus abdominis, external and internal obliques, and spinal erectors while they did crunches at rep speeds of four seconds, two seconds, 1.5 seconds, one second or as fast as possible. They reported in a 2008 issue of the Journal of Strength & Conditioning Research that as the rep speed increased, so did the activity of all four muscles. The greatest boost occurred in subjects’ external obliques, which were hardly involved in the crunch at slower speeds but increased by more than six times at the fastest speed.
So don’t fail to vary your rep speed. The fast reps will help recruit more muscle fibers in the midsection and turn the crunch, which targets the rectus abdominis, into an effective oblique exercise. M&F
