What is included in the MMD1?

The correct answer, which identifies what is included in the MMD1, is "Verticals." In the context of physical training, MMD1 likely refers to a specific assessment or training module that evaluates performance metrics related to vertical jump strength, a common measurement in athletic training. Vertical jumps encompass various movements that assess an individual's leg power and explosive strength, both of which are key components of overall athletic performance.

This makes "Verticals" the most appropriate choice as it directly relates to plyometric and explosive training often featured in strength and conditioning programs.

While back squats, push presses, and leg extensions are all valuable exercises for building strength, endurance, and muscle, they do not specifically align with the typical metrics assessed in a module labeled MMD1. Instead, those exercises are generally more focused on hypertrophy or strength in specific muscle groups rather than on explosive power and vertical leap capabilities. Thus, the choice of "Verticals" clearly fits within the context of what is likely evaluated in the MMD1 training or assessment module.
