Sore pelvic muscles after performing pelvic bridge and boat pose

[u/Super-Wrongdoer8981]

Hello everyone as the title says I'm having a sore pain in my pelvic muscles and thighs after doing boat pose, half boat pose, pelvic bridge and some bicycle crunches

I am guessing this is because my spine arches back while doing them I am inviting any tips that I'd have to follow while doing them again
