Antagonistic training refers to:working an upper body muscle then moving to a lower body muscleworking opposite musclesworking right side muscles then left side musclesnone of the above

Antagonistic training refers to:

1. working an upper body muscle then moving to a lower body muscle
2. working opposite muscles
3. working right side muscles then left side muscles
4. none of the above

Step-by-step analysis:

1. Option 1: working an upper body muscle then moving to a lower body muscle

   • This option describes a method of alternating between different parts of the body but does not specifically address the concept of antagonistic muscles.

2. Option 2: working opposite muscles

   • Antagonistic muscles are pairs of muscles that work opposite each other. For example, the biceps and triceps are antagonistic muscles because one contracts while the other relaxes to create movement.

3. Option 3: working right side muscles then left side muscles

   • This option describes a method of alternating between sides of the body but does not specifically address the concept of antagonistic muscles.

4. Option 4: none of the above

   • This option would be correct only if none of the previous options accurately described antagonistic training.

Given the definition of antagonistic muscles, the correct answer is:

2. working opposite muscles
