Ive had a torn knee tendon for 6months with another 2 months until it is completely healed (hopefully)

Squats and deadlifts are 2 of the most recommended workouts here but sadly i cant perform them at the moment.

I do arms twice a week and chest twice a week.

Arms: Barbell curls Concentration curls Skull crusher Tri pulldown Lat pulldown Chin ups Deltoid flys?

Chest: Bench Flys Pushups Rows Cable flys Chest press

Ive noticed a stall in my progress. What else can i add to my training in the meantime?
