He's a small guy physcially, Sid Paras are big guys, by big i mean big structures, big boned much heavier too. Totally different weight class, plus they're taller.
Asim is more muscular and physically stronger than Paras. Paras just has a few inches of height difference.
Asim can hold his own against Shukla as well. Took him down in sultani akhada wrestling after all.
