The exclusive flexibility development video course "SPLITS PACKAGE" in English, based on the method of the most flexible person on the planet, will help you quickly achieve your goal.
The video course consists of 2 videos with a total duration of 18 minutes, plus 2 bonus training videos with a total duration of 47 minutes, which you will receive after purchasing the course.

Included in the training package you purchase:

1) "Theory and rules of splits training" — duration: 11 minutes. This is the most important video in the "SPLITS PACKAGE" — the theoretical part of stretching training. Without it, even the MOST EFFECTIVE exercise will not be as useful as after watching this information. The effectiveness of an exercise depends on how you perform it — almost any exercise can be harmful if done incorrectly or simply ineffective. After this video, everything will become clear.

2) Training "Active side split" — duration: 10 minutes. Here you will learn several of the most important and challenging exercises to teach your body the side split as a natural form of mobility in a short time. It is important to first watch the video "Theory and rules of splits training" before doing this workout.

BONUS! If you contact me after purchasing this course (contacts below), you will receive 2 additional training videos with a total duration of 47 minutes as a gift:

Training "Passive BOTH splits" — duration: 25 minutes. These are light, safe, and effective exercises that I professionally compiled into one easy routine. Based on my coaching experience since 2009, I selected the most effective passive exercises to prepare the body for the two other trainings in this package — "Active side split" and "Active front split".

You will also receive the training "Active front split" — duration: 22 minutes. Here you will learn several of the most important and challenging exercises to teach your body the front split as a natural mobility in a short time. It is important to first watch the video "Theory and rules of splits training" before doing this workout.

Summary: First review the theory, then perform the "Passive BOTH splits" workout several times (no more than once per day at the beginner level), then either the "Active front split" or "Active side split", alternating preferably on the same day.
However, listen to your body and sensations — the order of active trainings doesn’t matter.
