The BEST weight to use for weight training in order to increase strength is one that is challenging but still allows for proper form.
Explanation;
Strength training is a type of physical exercise specializing in the use of resistance to induce muscular contraction which builds the strength, anaerobic endurance, and size of skeletal muscles.
Strength training uses resistance, like free weights, weight machines, resistance bands, or a person's own weight, to build muscles and strength.
Besides building stronger muscles, strength training can:
- improve overall fitness
- increase lean body mass (more muscle, less fat)
- burn more calories
- make bones stronger
- improve mental health
