back on the ground butterfly

i noticed i am not very flexible in the frog stretch so i decided to put extra limbering in the middle of the week i was thinking about butterfly with my back on the ground with plates on my knees or diamond frog with feets near the groin (and partener help) so i can deepen the regular frog stretch 

any comments or suggestions 

thank you

Extra limbering during the week, especially around your other training sessions, is a great idea, Oussama! Be mindful of not doing too much deep stretching (each stretch course 1x/week), but some additional pancake and frog work would be beneficial. 

yes  the session is just one week since i noticed in the forum they keep saying u can do just some limbering a thought i will give extra to the frog especially wht about the exercise i referred to ?

Those stretches sound fine to add as some additional limbering. 

thanks a lot
