Foods to improve sex drive in males

But while the additional calories burnt may not be as out of this world as some people might have you believe, you'll certainly be better off, which will put you on track to where you want to go! Unfortunetly there's no absolute 100% concrete number that can be given as to how many calories muscle burns for all of us, but there are estimates based on research! So if you're into crunching figures, you could say a kilogram of muscle means you'll burn 207 extra calories everyday (or a pound of muscle equates to an extra 94 calories burnt). It's difficult to determine the difference between which calories were burnt from exercise and which were chewed up thanks to the added muscle mass.
Also, the additional muscle the men gained after the 8 weeks (remembering it was an 18 week study all up) didn't equate to further calories burnt. Another study into 13 healthy men aged between 50-65 years, found that 16 weeks of heavy resistance strength training increased their resting metabolic rate (calories required to keep the body functioning daily) and increased their fat free mass, aka lean muscle! The authors also point out that nervous system activity played a role in the increases of the men's metabolic rates - not just the added muscle mass. This is something else we need to consider when trying to pin point a number of calories that muscle mass burns. The research suggests muscle burns about 13 calories per kilogram or about 6 calories per pound (3). And this is assuming that you're training regularly and have a constant rate of muscle protein turnover. It's not for someone sitting on the couch living and relying on their high school powerlifting hey day! After a brutal training session, protein turnover is increased due to the damaged muscle cells that need to be fixed. Think of it like this - two guys, one with a motorbike and one with a 4WD, burst through a large mud puddle. And even though it's only small, training with weights will increase your daily calories burnt. But the important part is that the more muscle you have, the more calories you will burn after a workout. But if it's just fat loss you're after, then combine your weight lifting with high intensity interval training and a good diet plan (that I can help with) and you're ready to rock and roll!
Puberty is the name given to the transition between boy and man and lots of changes occur and the hormone levels become much more favorable for building muscle.
Height growth continues but slows further and natural muscle growth (without aid of weightlifting) continues.
The above chart shows two of the important hormones necessary for gaining muscle mass and how they vary with age.
There are a lot of excellent reasons to exercise and in my opinion, bodyweight type workouts are beneficial as early as the early teens.
The answer to this question simply lies in doing all three angles along with an understanding of the following 3 concepts: Line of resistance, Joint motion and Self-palpation. Any chest movement from an incline position on a bench will have a greater emphasis on the upper chest fibers.
Furthermore, there's even been a study that showed that a supine or reverse grip led to an increase in upper chest activation during a flat bench press (6). While the research can delineate between upper, middle and lower chest activity (2, 9), I've personally that there isn't much difference in middle and lower chest work, but that the main difference comes with incline work for the upper fibers of the chest. The information provided in this article is for educational and informational purposes only and does not serve as a replacement to care provided by your own personal health care team or physician. One of the many ways to vary chest training is through the manipulation of the angles in which the pecs are trained. Line of resistance deals with the line of gravity's pull relative to the targetted muscle's angle of pull on one's body.
The key is in using different platforms of resistance such as barbell and dumbbell work to get the job done.


Interestingly, this finding supports my joint motion concept, being that when one's grip is supinated or reversed (palms facing up), this changes the motion at the shoulder to be flexion. This changes the motion to shoulder flexion and with the bench at a moderate incline, you will double the activity in the clavicular fibers.
Essentially, any kind of flat bench press exercise, be it with a barbell or dumbbells will sufficiently work this area of the chest. So rather than thinking in exclusivity or isolatory terms regarding working upper, middle and lower chest, I'd recommend shifting the train of thought to "emphasizing" upper, middle or lower chest.

Common knowledge has it that flat bench press targets the middle chest, incline bench press targets the upper chest or clavicular fibers and decline bench press targets the lower fibers of the pectorals. While some research has found no significant difference in upper pectoral recruitment between decline and incline chest press (4), this shouldn't discourage anyone from still including incline bench work. Shoulder flexion is a strong initiater and activator of the clavicular fibers of the pectoralis major (5). Be sure to keep the elbows close to the body as this will further increase upper chest development since the arms will be in a more horizontally adducted position, which will increase the tension in the clavicular fibers of the pectoralis major. One study did find that decline bench press led to greater activation of the lower pectoralis major, however this was in comparison to incline bench press only (4). In reality, the entire muscle will contract, but certain areas will be recruited differently depending on the exercise performed.

However, in this article, a combination of research-based information and personal knowledge will be used to come to a concrete conclusion along with workout recommendations regarding chest training for optimal development.
Finally, self-palpation maybe the simplest, but most effective way to know if an exercise is effectively targetting a certain or particular segment of the chest.
In fact, other research has shown that there was greater activity in the upper chest during an incline chest press vs.
Either way, I personally find that the decline bench press is a great exercise not only for emphasizing the lower pecs, but also, allowing greater weight to be lifted.

Self-palpation is simply touching or feeling the targetted muscle group during the intended exercise motion to make sure it's "firing" by getting taut and tense. Palpate your upper chest fibers and simply take your arm and raise it in front of you to shoulder level keeping your arm in line with your shoulder. I find that one can lift their heaviest when performing decline presses since the range of motion will be slightly reduced as well as greater surface area of the chest being engaged due to the bar path line of resistance being lower on the chest. If the muscle is flacid, this is usually a sign that it's not being significantly used in the exercise. Logically, this makes sense from a joint motion perspective since the clavicular fibers are active in shoulder internal rotation, horizontal adduction and flexion (5). What you will notice is a distinct and isolated contraction of the clavicular fibers of the chest.


Additionally, it has been found that activity of the sternal head of the pectoralis major decreased as grip width decreased when using a overhand grip, but the activity of the sternal head did not decrease when using an underhand grip as grip width decreased (6). I also find that decline bench press is less strenuous on the shoulders since the resistance is angled in a position where it's not directly in line with the shoulder.
Additionally, the inclusion of various chest fly exercises are also in order for attaining full development of the chest.

A narrow hand spacing naturally moves the arms into a slightly more internally rotated position and more importantly, more towards horizontal adduction, which creates a "cramming" effect that increases muscle tension based on the shortening aspect of muscle contraction along the muscle length-tension relationship (5).
In fact, when asked what exercises best train the upper pecs, I typically get a surprised look when I recommend front dumbbell raises. I personally find that fly work helps carve in those chest striations as well as pump up the chest even more after the compound chest exercises (i.e.
While your'e doing the movement, check and feel to see if the targetted muscle group is becoming actively engaged by getting harder to your touch. More importantly, the clavicular portion of the pectoralis major lies close to the anterior deltoid, so it works closely with it as well. Many know this exercise is great for the anterior delts, but remember, it's shoulder flexion, and from a biomechanical standpoint, this strongly recruits the clavicular fibers of the pectoralis major (5).
In agreement, it was found that close-grip push-ups led to greater activity of the pectoralis major and triceps brachii compared to wider grip push-ups (3). The biggest thing with training the chest at varying angles is that typically the entire chest musculature will fire, but the difference comes in the way of which segment or area is being "emphasized." In fact, research has suggested that it is possible to emphasize particular segments of a muscle group with varying exercises and angles of lifts (1).
This is important to know, since chest press technique can further partition out the upper chest from the anterior delts to be emphasized more. While push-ups are different than bench pressing due to push-ups using more core musculature to support the body in a plank position, the motions are very similiar. Additionally, dips are a great exercise for chest development and in agreement with this article, many of Arnold Schwarzenegger's recommendations in his book "The New Encyclopedia of Modern Bodybuilding," are quite similar to this article (8).
In fact, all too often I hear of someone wanting to feel sore in the upper chest, but they end up getting sore in the front delts only. In fact, it was found that as the angle of inclination increased during a bench press, the activity of the sternal head decreased (9). For inner chest, he recommends holding the top of contraction for several seconds and using a close-grip, while for outer chest, he recommends focusing on the lower range of motion, a wider grip and the lower three-quarter movement of a chest exercise (8).
Additionally, for rib cage development, he also recommended barbell and dumbbell pullovers (8). Having the shoulders slightly drawn down and back (via poking your chest out) will enhance glenohumeral alignment and stability.
He's definitely correct not only from experience, but research has shown that pullovers are great exercise for the pectoralis major (7). Secondly, it will place the chest in the "line of fire" so to speak, so your anterior delts will still get worked, but not overworked. In further support, another study found that a moderate incline of 44 degrees led to greater activity of the clavicular head compared with 0 and 28 degrees (9).
