Types of Crunches

  • The reverse crunch or dragon flag (popularized by Bruce Lee and also Sylvester Stallone in his movie Rocky 4). Begin lying horizontal on a bench. The arms are used to hold the underside of the bench to anchor the shoulders to it to prevent rolling forward. The rest of the body inferior to the scapulae is then pulled from the bench. Beginning with legs flexed, the legs can be extended slowly to increase the difficulty of the movement (and tension on the core muscles) due to moving the weight further from the levers. Throughout the movement the legs and hips are meant to remain locked while movement occurs in the abdominal region.
  • The twisting crunch is performed by lifting one shoulder at a time. More emphasis is placed on the obliques.
  • The Thai Crunch is performed by hitting the stomach after full contraction. This variation is used by Muay Thai fighters to condition the core to take hits from punches or knees.
  • The cable crunch is performed while kneeling upright by curling the body to pull down on a cable machine. The hips are kept motionless, so the bodyweight does not assist the movement.
  • The bicycle crunch is performed by bringing together alternating elbows and knees, resulting in a leg motion similar to pedaling a bicycle.

Carnitine, also known as L-carnitine, is a compound biosynthesized from the amino acids lysine and methionine.It helps in the consumption and disposal of fat in the body because it is responsible for the transport of fatty acids.

The highest concentrations of carnitine are found in red meat and dairy products. Other natural sources of carnitine include nuts and seeds (e.g. pumpkin, sunflower, sesame), legumes or pulses (beans, peas, lentils, peanuts), vegetables (artichokes, asparagus, beet greens, broccoli, brussels sprouts, collard greens, garlic, mustard greens, okra, parsley), fruits (apricots, bananas), cereals (buckwheat, corn, millet, oatmeal, rice bran, rye, whole wheat, wheat bran, wheat germ) and other 'health' foods (bee pollen, brewer's yeast, carob, and kale).

Whey Protein

Whey protein is the name for a collection of globular proteins that can be isolated from whey, a by-product of cheese manufactured from cow's milk. It is typically a mixture of beta-lactoglobulin (~65%), alpha-lactalbumin (~25%), and serum albumin (~8%), which are soluble in their native forms, independent of pH. Whey has the highest Biological Value (BV) of any known protein.

Whey protein typically comes in three major forms: concentrate, isolate and hydrolysate. Whey protein concentrates contain a low level of fat and cholesterol but generally have higher levels of bioactive compounds, and carbohydrates in the form of lactose — they are 29%-89% protein by weight. Isolates are processed to remove the fat, and lactose, but are usually lower in bioactive compounds as well — they are 90%+ protein by weight. Both of these types are mild to slightly milky in taste. Hydrolysates are predigested, partially hydrolyzed whey proteins which consequently are more easily absorbed, but their cost is generally higher.

Fit Lad of the Day


Glutathione (GSH) is a tripeptide. It contains an unusual peptide linkage between the amine group of cysteine and the carboxyl group of the glutamate side chain. Glutathione, an antioxidant, protects cells from toxins such as free radicals.

Supplementing has been difficult, as research suggests that glutathione taken orally is not well absorbed across the GI tract. In a study of acute oral administration of a very large dose (3 grams) of oral glutathione, Witschi and coworkers found that "it is not possible to increase circulating glutathione to a clinically beneficial extent by the oral administration of a single dose of 3 g of glutathione."

However, tissue and serum glutathione concentrations can be raised by increased intake of the precursor cysteine. Glutathione precursors rich in cysteine include Acetylcysteine undenatured whey protein and N-acetyl-cysteine
