In a deep tissue massage, you apply pressure with your hands, arms, and body weight on another person’s muscles. Start by making sure the person is relaxed.
1. Relax The Person
Covers the person well. Generally, people should not be fully dressed for a deep tissue massage and most of them are not comfortable with fully exposed. Therefore, you should cover the areas that you are not working on at the moment to allow the person to feel more relaxed.
Generally, you will start with the person face down on the table.
Apply massage oil. Apply some oil on your hands. You do not need to use a large amount of oil to do a deep massage. Make sweeping strokes along the person’s back to spread the oil. The heat from the massage will also make it melt.
Ask the person if they have any allergies to any particular oil.
Use a little glide. Run your hands carefully over the person’s skin. You should not start working with a deep tissue massage, as it will cause the person to tense up. Slightly sliding your hands allows the person to warm up and relax so that you can move toward the deep tissue massage.
Basically, you will use your whole hand to rub over the area where you will be doing the deep tissue massage. At that point, you will only apply light pressure, just enough so that the person feels your hands.
Massage your fingers together. Use your whole hand with your fingers together. Spreading your fingers is more likely to pinch the muscle, which can be painful. Imagine sculpting clay, whether you slide your hands over the person or continue with the deep tissue massage. 
2. Apply Pressure To The Back
Use the palm of your hand. As you go through the first few light movements, you will feel your muscles begin to warm up. When that happens, you can use the palm of your hand and the weight of your body to begin adding pressure to the movements. Move your hand along the muscle that runs to the side of your spine and along your back. Apply pressure in slow, even movements.
Don’t apply pressure to any bone or spine.
Massage with your fingertips. Once the muscles warm up a bit more, start using your fingertips. You can use very small movements to the sides or a light rocking motion along the muscles keeping the fingertips together. Run your hands from your lower back to your shoulder.
Use your forearm to apply pressure to your back. Starting at the shoulder, place your forearm on the inside of your back. Apply pressure with your body weight and run your forearm over the muscle that runs along the outside of your spine. Your forearm should slide from your upper body toward your back in one fluid motion.
Go sideways along the lower back. As your forearm reaches your lower back, rotate your arm laterally so that you come just above your glutes. Take your arm behind your back along the outer edge and around your shoulder. With your hand toward the floor, move your arm toward your shoulder toward your chest as you finish.
3. Massaging The Arms And Legs
Use your forearm to apply pressure to your leg. Starting above the ankle on the back of the leg, use the forearm to add pressure to the movements. The forearm should be along the leg and you should add pressure with your body weight. Move behind your calf and thigh, and support your arm for a moment just below your buttocks. Slide your arm in a fluid motion around your hip.
Apply pressure to the calf with your thumbs. Place your hands on both sides of your calf with your thumbs in the middle, one behind the other. While applying pressure, move your thumbs up your calf, staying in the middle groove.
The muscles along the back of the calf are actually a single muscle, the gastrocnemius muscle, but it has two heads. That means there is a groove in the middle of it that the thumbs must follow.
Another thing you can do is use your knuckles.
Press down on the upper arm with the base of your hand. Start at the elbow with the person lying on their back and move the arm toward the shoulder with the base of the hand. Use your body weight to apply pressure.
You can also use your knuckles on the arm to apply pressure. Use small circular motions.
Run your fingers up the forearm. With your thumb on one side and the rest of your fingers on the other side of the forearm (inside or outside), apply pressure to both sides. Move your hand up your arm toward your elbow.
You can also use both thumbs on the top of the forearm. Put your thumbs in a single line, not close to each other. Pass them in the middle of the forearm applying pressure.
Massage the hand with your thumbs. Place both thumbs close to each other on the inside of your wrist. Move them together slowly over the wrist and along the life lines of the hand. Pay special attention to muscle areas, including the area around the base of the thumb.
