Last month i was diagnosed with mild mvp and trivial mitral regurgitation. everything else normal. can i continue my weight lifting exercises in gym?

Choices & will drive: hydraulic valve loads high while doing each & every lift. During the lift, varying with technique/strategy, both pulmonary & system BP's dramatically ↑, in turn increasing blood pressure differential on all the valve leaflets. The ↑ed pressure drives any prolapse & leaks. Avoid any breath holding (narrowing of vocal cords); bad technique for health. Also get & closely inspect all the echo videos.
