Deadlifts build back strength. Deadlifts teach you to keep your lower back rigid against a load. Keeping your back straight is critical to avoid injuries when lifting heavy objects from the floor
What’s a Deadlift? Pull the barbell from the floor with both hands until your body is fully extended. Deadlift by pushing from the heels, and bringing your hips forward. Not by pulling with your lower back.
Different types of exercises are
Aerobic (e.g. walking, swimming)
Anaerobic (e.g. sprinting)
Isometric (e.g. lifting weights)
Resistance (hand weights)
1.Aerobic (Endurance) training:
Aerobic exercises are those that require a steady supply of oxygen, to sustain the energy giving powers of the muscles .An aerobic exercise is any activity performed for a minimum of 20 minutes maintaining a heart rate between 70%-80% of maximum heart rate with chief energy sources being oxygen and body fat.
2.Strength or Resistance training
Types of muscle contractions: There are three types of muscle contractions involved in strength training:
Isometric contractions. There is no change in the length of the muscle. For example, pushing against a wall.
Concentric contractions. These movements shorten muscles (for example, the up phase of when the bicep curls up while lifting weights).
Eccentric contractions. These movements lengthen muscles (the down phase as the weights are lowered).
3. Flexibility training (Stretching):
It is now recommended that one should perform stretching exercises for 10 to 12 minutes at least three times a week. The following are some general guidelines:
When stretching, exhale and extend the muscles to the not pain, and hold for 20 to 60 seconds. (Beginners may need to start with a 5 to 10 second stretch)
Breath evenly and constantly while holding the stretch
Inhale when returning to a relaxed position. (Holding ones breath defeats the purpose; it causes muscle contraction and raises blood pressure.)
4.Resistance training
It involves providing some form of resistance to the contracting muscles to stimulate the body for increased strength. Equipment used for resistance training takes multiple forms, including hand weights, pulleys, hydraulic, elastic, rubber, fibreglass, and magnetic equipment.

A great upper-region chest exercise. By using dumbbells, you can achieve a better stretch at the bottom of the movement and a stronger contraction at the top. Being able to move the weight through a greater range of motion recruits more muscle fibers, resulting in greater muscle gains.
1.Grasp a pair of dumbbells and lie back on a 45-degree incline bench.
2. To achieve a full contraction and to keep your shoulders out of the movement as much as possible, use a palms-in grip
3.Keeping your elbows in a natural position and your forearms perpendicular to the floor, begin pressing the dumbbells up.
4.Barely touch them together at the top while squeezing your chest forcefully.
5.After a brief pause, slowly lower the weights back down to the starting position and repeat. Use a full range of motion.
