Stretching Legs of Titan Boxer Briefs?

Training Powerlifting
1

hi guys, i am a powerlifter, and I want to wear titan boxer single ply briefs underneath my boss suit, I lift in a double ply fed. Now The briefs are very tight, size 40 I weigh 210lbs atm compete in 200lb class (90ks), but its nearly going on, jsut the legs need to stretch about 1 cm more so it can go up my legs.

Everytime I try them on they stretch so every time go up further and further. However can I use a football and a pump to stretch out the legs, and how easy and how long does it take thank you.
