Research confirms that training one limb at a time forces the recruitment of more muscle fibers and produces more force, since a limb working alone requires more effort to move a weight from point A to point B than when it’s working in concert with another limb. Consider the barbell curl: A lifter who can curl a 100-pound barbell for 10 reps can likely perform dumbbell curls with 55 or 60 pounds in each hand because of the resultant increase in muscle fiber recruitment. In addition, unilateral training tends to maximize the number of growth-prone fast-twitch fibers that are called into play.
The third and final phase of the “25% Stronger” program helps you max out your strength levels by gradually decreasing the volume of your workouts while increasing the amount of weight you move. You’ll begin the last phase at the top end of the strength range (seven reps). Each week, you’ll perform fewer sets and reps - five of five, four of four and finally the last week in which you perform three sets of three - so your body is fresh for the final tests in Week 13.
In competitive bodybuilding, bodybuilders aspire to develop and maintain an aesthetically pleasing body and balanced physique.[16][17] In prejudging, competitors do a series of mandatory poses: the front lat spread, rear lat spread, front double biceps, back double biceps, side chest, side triceps, Most Muscular (men only), abdominals and thighs. Each competitor also performs a personal choreographed routine to display their physique. A posedown is usually held at the end of a posing round, while judges are finishing their scoring. Bodybuilders usually spend a lot of time practising their posing in front of mirrors or under the guidance of their coach.
An article by Muscle & Fitness magazine, "Overtrain for Big Gains", claimed that overtraining for a brief period can be beneficial. Overtraining can be used advantageously, as when a bodybuilder is purposely overtrained for a brief period of time to super compensate during a regeneration phase. These are known as "shock micro-cycles" and were a key training technique used by Soviet athletes.[53]
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.
