Resistance training also burns calories.
Whereas it seems that cardio burns more calories, weight lifting shapes your body.
Building muscle mass also increases your RMR (Resting Metabolic Rate) which means that if you practice strength training for long enough, your body at rest will burn more calories in the future.
A good investment.
It improves your balance.
Adults over 60 years old show 34% less falls if they have been training with weights in the past.

Strength training plays an important role too by decreasing your blood pressure, decreasing your 'bad' cholesterol and helping you manage your sugar levels.
It increases your range of motion.
ROM (Range Of Motion) stands for how far you can move or stretch a part of your body, such as a joint or a muscle.
When exercises are performed with a full ROM, it will increase it and also strengthens your joints, muscles, ligaments and tendons.
Performing full ROM will also emphases hypertrophy.

An improvement that seems to be linked to self-esteem, feeling more capable of coping and goals achievement.
'Molecular changes in the lifters’ muscles and brain likely also occurred and contributed to improvements in their moods'.
It improves sleep quality.
23 000 adults in Germany got tested. They reported the amount of resistance training done in a week and how they felt about sleep.
Searchers noted that whenever excise has been done, there were less 'poor' or 'very poor' sleep.
This might be explained by Adenosine, a molecule that is broken down into ATP (Adenosine Tri Phosphate) to be used as energy. When ATP is naturally depleted through activity, it breaks back down into adenosine and at that point, tends to cause drowsiness.
