Exploring the Distinctions Between Frog Splits and Full Side (Middle) Splits:
The primary distinction between a Frog split and a full side (middle) split lies in the position of the knees. In a Frog split, the knees are bent, whereas in a middle (side) split, the knees are straight. This difference is crucial because straightening the knees stretches the hamstrings, with a greater emphasis on the middle hamstring rather than the lateral hamstring. Additionally, the Gracilis, an adductor muscle that crosses the knee, is also stretched in a side split.
When performing a Frog split with bent knees, the hamstrings and the Gracilis, both knee flexors, are in a shortened state, meaning they aren't being significantly stretched. However, straightening the knees during a side split elongates these muscles, allowing them to be effectively stretched. This key difference highlights the unique muscle engagement and stretching involved in each type of split.
Why You Can Achieve a Frog Split But Not a Full Side Split:
If you've mastered the Frog split but find the side split elusive, there's a clear explanation. Achieving a split requires flexibility in various muscles, and the anatomy of a side split reveals that certain muscles are stretched with straight (extended) knees, while others require bent knees.
Key muscles involved, such as the medial hamstrings (
semitendinosus and semimembranosus) and the gracilis, cross the knee and act as flexors. This means that when the knees are extended, these muscles are stretched further.
If you're able to perform a Frog split but struggle with a full side split, it indicates a flexibility issue with one or more of these muscles. Fortunately, with targeted stretching techniques like the Zaichik Stretching Techniques, you can isolate these muscles and enhance their flexibility, bridging the gap from a Frog split to a full side split.
Focusing on the gracilis and middle hamstrings, as you do in a Frog split, can accelerate your progress toward a side split. The EasyFlexibility Side Splits programs specifically target these and other relevant muscles to facilitate achieving your side split efficiently, safely, and easily."
