In bodybuilding and fitness, the deltoid muscles play a special part. Despite the fact that the muscle area belongs to small groups, it is second only to the biceps in terms of training frequency. The reason lies not only in the importance of the deltoid muscles in the anatomy but also in improving the aesthetics of the figure. Understanding the functions and features of the deltoid bands allows you to maximize the effectiveness of the training process and significantly reduce the injury risk. The deltoid muscles consist of three heads (bundles): The anterior head (anterior bundle) attaches to the humerus and is responsible for lifting the arm forward. The middle head (lateral bundle) is attached to the acromion of the scapula and allows the arm to be lifted sideways. The posterior head (posterior bundle) is attached to the scapula and allows the arm to be moved backward. The deltoid muscle covers the shoulder joint. The muscle is thick, triangular in shape, with the base up and the apex down. It consists of large muscle bundles, which fan-like converge at the apex. It starts from the clavicle and scapula and attaches to the deltoid tuberosity of the humerus. In training the deltoid muscles, it is very important to pump all three bundles equally. This will protect the shoulder joint from injuries. The deltoid muscle bundles have different functions, so you cannot work them all with just one exercise: you must include at least three movements in your workout. You must correctly select exercises for pumping the front, middle and rear bundles. Choose one exercise from each category and add them to your workouts. Shoulders should be trained no more than twice a week (once is enough for beginners), this will allow the muscles to fully recover for the next workout. Here is some basic exercises for deltoids: The army bench press or barbell/dumbbell press in standing or sitting position (middle, front). Bench press from behind the head while seated (middle, front). Chin-up or 'broach' barbell pull (middle, front). Lee Heini pulls (back, middle). Arnold press (front, middle).

One of the most important running muscles is the quadriceps - the large muscle at the front of the thigh. It has been scientifically proven that regular strength training improves workout performance and reduces the risk of injury, as well as strengthens your back, and leg muscles, making your running more productive. The quads, also known as the quadriceps muscle, is a group of muscles located at the front of the leg above the knee. It is one of the largest and strongest muscles in your body that consists of four heads: fastus medialis (medial wide), vastus intermedius (intermediate wide), vastus lateralis (lateral), and rectus femoris (straight thigh muscle). Almost every action performed by the legs involves two or more heads of the quadriceps. The quadriceps muscle plays an important role at the beginning of the movement (quick start) and during ascent and descent in elevated positions - which is why you may experience painful sensations in this area of the leg after an intense uphill workout. According to researchers at the University of Delaware, strong quadriceps act as cushioning and can protect the knees and the entire musculature of the hip from common running injuries. Often many runners are injured because they have weak and underdeveloped quadriceps, so it is especially important to strengthen them. By training and strengthening the quads, you can get the following benefits when running: Increased speed. Strong quadriceps help you tackle steep hills and climbs more easily and make pushing off the ground more powerful, resulting in increased speed. Reduced injuries. According to research, poorly developed quadriceps are often associated with many running injuries. For example, a common injury such as the 'runner`s knee' results from weakness in these muscles, which are unable to stabilize the knee joint during the movement. Increased endurance. Strengthening the quadriceps muscle will make your running more effortless and efficient, which contributes to increased running volume and endurance. Training The quadriceps occupy 70% of the muscle mass of the leg, so it is their development that is fundamental in leg training. The main exercise for developing the quadriceps is the squat. But, for beginners, at the first stages of training, it is better to start with leg curls sitting in an exercise machine, leg press, and hyperextensions to strengthen the lower back, to avoid injuries, in order to prepare the base for the heavy squats. It is a good idea to include squats in your training plan after about six months of training.

The arm is one of the most important parts of the body. Arms muscles are only 10-15% of the mass of all muscles in the body. Your arms are not only divided into biceps and triceps but into 20-25 different muscle groups. For example, the biceps is a double flexor muscle attached to the shoulder and elbow. The triceps is a triple extensor muscle that occupies the back of the arm. In addition, pumping the arms implies an emphasis on the muscles of the forearm and shoulders. For example, when lifting dumbbells while standing, the load falls on the entire upper body - including the trapezoid. The situation is similar with triceps - extensions from behind the head involve the serrated muscles located in the armpit area. The best arm exercise is the exercise that makes you feel the biceps or triceps work. In order to quickly build muscles, it is not enough to perform lifts of heavy dumbbells, arching the whole body - the workout requires moderate weights, slow speed, and complete muscle control. For beginners and intermediate athletes, one arm workout per week is enough. On the rest of the training days, these muscles are involved in the work partly- the triceps are involved in push-ups, bench press, and other chest exercises, and the biceps are involved in pull-ups. The secret to successful arm muscle training is using multi-joint exercises to develop upper body musculature (such as push-ups and pull-ups). In fact, it is impossible to build large arms without having the proper level of development of the back, chest, and shoulders. The frequency of the training also plays a role. Even professionals are not recommended to work with their arms more than twice a week, and the total duration of arms training should not be more than 20-25 minutes - otherwise, overtraining will occur, which negatively affects the growth of muscles. The development of neuromuscular communication - is important too. It is necessary to raise and lower the weight due to the conscious work of the biceps or triceps, and not simply due to inertia. This will help to build up the muscles of the arms as quickly as possible - in the end, they respond quite well to regular training. Training Pushup. Put your hands and toes on the mat. Keep your arms straight, but don't lock your elbows. Align your feet making the straight line with your arms and core. Inhaling, bend your elbows and lower your chest to the ground slowly. Straighten your arms to lift your core up, exhaling. Half Handstand Variation. Begin with the downward-facing dog position. Walk your feet in closer to your hands. Keep your left foot on the ground, lifting onto the ball, and begin bending the knee. Lift the right leg and straighten it behind you. After taking a few hops, jump off the bent leg and lift the straight leg toward vertical. Keep flexing your lifted foot for engagement. Now, try to bring both heels to the wall. Keep breathing deeply while your head is down between your upper arms. Remember to engage your legs and reach up through your heels. Walk your legs down the wall. Then get back to the starting position with your feet on the ground. Make a deep squat and jump out. Jumps with Dumbbells. Stand with your feet shoulder wide and knees slightly bend, dumbbells in both hands. Bend your knees and squat down engaging gluteus, quads, and hamstrings to push the body up and off the floor. Keep your hands with weights straight down.

This time we suggest paying special attention to the chest muscles. It is this zone that many athletes want to pump, but it is not so easy to do and one classic chest press is not enough. Chest muscles are one of the most complex and largest muscle groups. Therefore, competent training must be a combination of basic and isolation exercises. Only in this way, it will be possible to load the muscles at different angles. Exercises with barbells are suitable for increasing muscle mass, and with dumbbells, on blocks and training machines - for improving the form and detailed elaboration. These exercises also activate the stabilizing muscles. Imagine that the chest muscle is a rubber band that connects the shoulder, collarbone, and sternum. If you lift your arm to the side and then pull the elastic band, it will move your shoulder forward. You do this movement all the time in your normal life like when you close a door, push something away with force, or elbow your jaw. Most pectoral muscle exercises repeat this movement. The only difference is that they also use a barbell, dumbbells, or crossover slings to create extra resistance. The chest muscle has two heads: an upper head (clavicle) and a lower head. Their functions are slightly different, and this is important. In order to have a symmetrical chest, you need to pump both heads. The fibers of the clavicular head are directed upward, so you need to move the shoulder forward from the bottom to the top for additional exercise. Many people believe that the more they pump their chest, the faster their muscle mass will increase. In fact, this has a negative effect on muscle growth. The muscle gets bigger during rest when the tissues are recovering from an active workout. There are a few tips on how to properly pump your pecs and not overtrain: Exercise no more than 2 times in 7 days. In between do physical exercises on other parts of the body; Do not exercise for more than 45 minutes, as this may cause muscle size and strong growth to regress. Exercises that help you to pump the chest muscles include: push-ups. bench presses. triceps push-ups. To pump your muscles evenly, alternate your exercises. The bench press is great, but you don't have to do it in every workout, because there are other good options. Choose the weight so that the last reps in an attempt are difficult. If you find it easy and your muscles don't tire, they won't grow. Avoid flying in the clouds during the workout: concentrate on the muscle work. It really helps you to pump it better. Perform 3-5 sets of 8-12 reps. Do not use weights that are too heavy. Especially at the beginning if you do not have a good command of technique.

The hips are some of the strongest muscles in the human body. They keep the torso upright, control the hip and knee joints, and are engaged during various activities and even at rest. Their proper functioning is extremely important, and anyone should know how they function. The muscles located on the hip are involved in both hip and knee movements, providing different positions of the hip in space depending on the proximal or distal support. Topographically, the hipі are divided into three groups. The anterior group includes the flexors: the quadriceps and the tailor muscle. The medial group consists of the hip drive muscles: the comb, the long, short, big adductor, and the thin muscle. The posterior group includes the hip extensors: biceps femoris, semitendinosus, and semi-perineal. The lateral outer and inner thigh muscles are considered antagonistic pairs: while one group is working, the other group relaxes. The abductors, including the middle gluteal, small gluteal, thigh broad fascia tensor, pear, and tail muscles are responsible for your leg movements from the middle of your body. Essentially, whenever you take a step to the side or turn your foot on the bed, you are activating the abductors. The inner thigh muscles, particularly the large adductor, small adductor, short adductor, and long adductor muscles perform the opposite task, working whenever you move your leg toward the center of your body. Strong and injury-resistant athletes have well-trained hip muscles. This is very important when it comes to fast sports with a lot of lateral movements, such as tennis or basketball, but also when you want to work out without pain. If your goal is to strengthen your hip muscles, which is really important, but you don't have your favorite leg workout, we will share some great exercises with you. Wide Squats. Every leg workout should include different variations of squats. This exercise targets the lower body, including the inner and outer thighs. But to really engage your thigh muscles, you should do deep squats with your legs turned outward. Sumo Deadlift. The Sumo deadlift is based on a similar leg position as in the wide squat. However, it is the external rotation of the thigh muscles that results in increased involvement of the inner and outer thighs. Side Leg Raises. A 2005 study published in the Journal of Orthopedic and Sports Physical Therapy found that side leg raises without weights are just as effective as other weighted exercises. Side Leg Pull-Ups. The pull-up exercise can be done anywhere because you don't need anything but a comfortable mat. This is a great exercise that you can add to your daily home workout routine.
