After session 12, consider whether you need to increase the weight for any particular exercise. If you can comfortably do more than the RM of 12 exercises, increase the weight by a modest amount, say two pounds or a kilogram for isolation exercise muscles such as triceps and biceps, and 5 pounds or 2.5.kilograms for compound and large muscle group exercises like squats and deadlifts. When using dumbbells, this would apply to each one. Don’t increase the number of sets beyond 3 at this time.
Resistance training or lifting weights is a common practice in the world of people who want to get bigger and stronger. To someone who wants to lose weight, it could seem almost counterproductive to put on muscle weight when your true goal is to lose weight. The truth of the matter is that you want to lose fat, and putting on muscle can help you accomplish that goal.
Major variants: incline ~ (more emphasis on the upper pectorals), decline ~ (more emphasis on the lower pectorals), narrow grip ~ (more emphasis on the triceps), push-up (face down using the body weight), neck press (with the bar over the neck, to isolate the pectorals), vertical dips (using parallel dip bars) or horizontal dips (using two benches with arms on the near bench and feet on the far bench, and dropping the buttocks to the floor and pushing back up.)
Walking into a gym to work-out for the first time can be intimidating, especially if you don't have proper guidance. Many new lifters either find themselves in that situation or are just training at home on some flimsy bench with a bar and a few plates. So, mistakes are common. Mistakes in terms of the exercises you're doing, how long you work out each day, how many days per week, the exercise form you're using, not to mention your eating habits.
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.
