Simply knowing where you stand can help your efforts tremendously. In exchange for a few bucks and a little pain, you'll receive health benchmarks on things like cholesterol and triglycerides, blood pressure, fasting glucose, and perhaps bone density for older women. These are concrete, quantifiable areas where you can track progress and see your hard work translate into results.
Simply stated, this means that if you perform an exercise using a complete range of motion, you can achieve a maximal effect in the process of muscle breakdown. Stressing the muscle over a long range of motion not only breaks down a much more significant amount of tissue, it also can help lead to more flexibility in the joints associated with the lifts.
The Russian twist is a type of exercise that is used to work the abdomen muscles by performing a twisting motion on the abdomen. This exercise is performed sitting on the floor with knees bent like in a "sit-up" position with the back typically kept off the floor at an angle of 45°. In this position, the extended arms are swung from one side to another in a twisting motion with or without weight.
Before hitting the sack, snack on a combination of slow-digesting casein protein and healthy fat. Casein coagulates in the gut, ensuring a steady supply of amino acids to slow catabolism as you sleep. About 30 minutes before bedtime, have 20–40g of casein protein powder or one cup of unsweetened low-fat cottage cheese (a stellar casein source) mixed with two tablespoons of flaxseed oil or one to two ounces of nuts or seeds.
When lifting it is essential to focus your mind completely on the muscle group you are attempting to work on. This makes sure that you are actually using the target muscle to lift the weight rather than accessory muscles or even momentum. This skill will develop with time, and as you progress in making that mind to muscle connection, your workouts will become much more productive and efficient.
