Shaykhana, I found 3 Muslim martial arts gyms with halal training. 90% wear tight tops & full or 3/4 length tights under shorts at or just above the knees. 10% wear tops and shorts without tights. If I cover my awrah, may I grapple with both groups? We stop for salah. Can we pray in these clothes?

Ustadh AbdulAziz al-Haqqan

From the navel to below the knee must be covered properly and loosely. Training with those whose tights cover this without showing the shape of the awrah is allowed, as for gazing upon the awrah of others (even men with men and women with women only) is not allowed as per the hadeeth.
