Question

1. what is the primary focus of strength training? cardiovascular health improving flexibility enhancing muscular strength and endurance weight management 2. what is the primary focus of muscular endurance? lifting heavy weights for a few repetitions keeping muscles working for a long time performing maximal effort against resistance building the ability to lift or move heavy objects 3. how does increased muscle mass contribute to overall body function? improves metabolism and body function improves your ability to run long distances spot reduces fat

Explanation:

1. Strength training aims to make muscles stronger and able to work for longer periods, so enhancing muscular strength and endurance is the primary focus. Cardiovascular health is more related to aerobic exercises, flexibility is targeted by stretching - type exercises, and while strength training can aid in weight management, it's not the main focus.
2. Muscular endurance is about a muscle's ability to perform repeated contractions or stay active over an extended time. Lifting heavy weights for a few repetitions is more about strength, performing maximal effort against resistance is also strength - related, and building the ability to lift or move heavy objects is strength - focused. Keeping muscles working for a long time is the essence of muscular endurance.
3. Increased muscle mass boosts metabolism because muscles require more energy at rest. It doesn't directly improve long - distance running ability (which is more related to cardiovascular endurance and leg muscle endurance for running), and spot reduction of fat is a myth; overall body fat reduction occurs through a combination of diet and exercise, not just increased muscle mass in a specific area.

Answer:

1. Enhancing muscular strength and endurance
2. Keeping muscles working for a long time
3. Improves metabolism and body function
