Support is not a sign of weakness. In fact, it shows your strength.
If your body is not capabable of doing a pose without modification or support, don’t push yourself into the posture. You can create unnecessary strain or injury.
In my 20’s, while giving birth, I sustained injury to my lower back. Due to this injury there are some poses where I need modification, and or support. Malasana is one of those poses for me.
While in this posture, and without support, I have to lean forward I experience discomfort in my hips, and a strain on my ankles because I have to spread my feet out so far to hold myself up.
The support of a block will gradually ease the tightness in my hips, and provide me the release, and flexibility I need to sit up straighter, and eventually sit in Malasana without discomfort.
Don’t strain, it’s not worth the pain.
