Standing trunk circle

In the past i had a lower abdominal strain and it took me a lot of time to fully recover.Now,when i perform movements like the Standing Trunk Circle or the Elevated thoracic bridge i feel an annoyance in my lower right abdominal and sometimes i feel sore in that particular spot for 2-3 days after. 
What strategy should i follow ? Should i strengthen my lower abdomen specifically and then progress once again with the GB routine ? 

Ps When i perform the Seal stretch while i am in pain i feel instantly better.

hey Athanasios, generally speaking, the scar tissue it is hard to stretch but it should be restored to a decent elongation state. If you have some problem I suggest you visit a physiotherapist and asking him an opinion.

Also, consider that when a strain happens it is due to tight and WEAK tissue. so increasing the strength of the abs will reduce the risk of a new strain.
