Why it takes time for our muscles to strengthen
Strength training is more physiologically intricate than initially realised. When we start to lift weights, our muscles are not the first to strengthen and change. However, our nervous systems do.
When we lift weights, we might feel some initial disappointment when our muscles do not quickly take shape. But weight training soon causes us to generate more muscular force where we can push, pull, and raise more weight than before, even though our muscles still look the same.

The cellular effects of resistance training
Scientists have known for some time that early increases in strength involve changes in the connections between the brain and muscles.
Particular bundles of neurons and nerve fibers carry commands from the brain's motor cortex to the spinal cord to the muscles. When the neural input to your muscles increases, the commands become more forceful, and the muscles should respond similarly. When strength training, the initial gains are about strengthening the reticulospinal tract. Only later do the muscles start to grow.

Pull-Ups Power
Pull-ups are a great way to test your strength-to-weight ratio and build your core and upper-body power.
They require a simple overhead bar as equipment, which is easily available.
Pull-Up by Machine Assist
Some people are unable to do pull-ups, even on a pull-up assist machine in the gym.
The 'assist' part of the pull-up aid machine might be the reason for the inability, as it can act as a 'crutch'.
Our Mind is the Obstacle
Many of us are stopped from being able to do pull-ups is our mistaken belief that we can't do it. The notion inside our mind that we can't do a pull-up is a major reason for our incapacity to do it.
Another reason most people cannot do pull-ups is the lack of regular practice. The gym-goers use equipment that narrows their muscle variations and doesn't replicate the real action of a pull-up.

Your Perception About Stress
With stress, the mind and the body are intrinsically linked. You can view stress as something that is wreaking havoc on your body (and it can) or as something that is giving you the strength and energy to overcome adversity.
Exposure to Stress
Regular exposure to stress in small quantities can prepare us to handle a big stressful event in our lives. Prepare yourself for stress by self-education about the stressful event, by doing some physically stressful activities like completing a marathon, or something you dread, like giving a speech.
Repeated exposure to mildly stressful conditions can alter your body’s biological response to stress, making you manage stress in a better way.

How muscle maintenance affects longevity
Muscle maintenance is vital to ensure healthy ageing.
In research with mice, researchers found that aerobic exercise changed how the animals consumed oxygen, metabolised sugar, and how tired they were when they weren't exercising. The mice were leaner and had fewer signs of inflammation.
Cells capable of regenerating tissue
The research team isolated muscle tissue and focused on satellite cells - stem cells that live in skeletal muscle and regenerate muscle throughout adulthood.
These cells are activated continuously, but over time become fatigued and stop renewing. Endurance exercise increases proteins involved in quieting and activating these satellite cells, which enable self-renewal or differentiation.
