Final answer:
The Eccentric RFE Split Squat is an exercise that can have variations that introduce additional weight or complexity. Options B, C, and D, such as the Goblet RFE, 2 DB RFE, and 2 DB with weighted vests, are such variations. The basic Split Squat is the foundational movement for these variations.
Step-by-step explanation:
The exercise in question is the Eccentric RFE Split Squat. A variation of this exercise could be any option that involves the same foundational movements with some modifications. In this context, the variations provided are:
- A) Split squat
- B) Goblet RFE
- C) 2 DB RFE
- D) 2 DB with weighted vests
Considering the eccentric nature of the original exercise, which focuses on the lowering phase, each variation could potentially incorporate that emphasis. However, the most direct variations would be those that add additional weight or complexity to the existing movement pattern—options B, C, and D fall under that category. However, option A, the basic Split Squat, serves as a foundation for the RFE (Rear Foot Elevated) version but doesn't introduce the eccentric emphasis specifically.
Thus, the exact variation would depend on whether the additional weight or complexity is also applied eccentrically.
