Pull ups and pushups weighted. How many?

I train 3 time a week: Monday Wednesday and Saturday. How many times a week I can train pull ups and pushups weighted. I have ankle weights 8 kg/ pair

Each time, but it depends on how many sets and reps and how close that is to failure. Where are you gonna put ankle weights on a pushup to make it harder? Why stick with pullups and pushups for so long that you need to weight them to progress, rather than a harder movement?

My record:

Chin ups and pull ups : 10

For dips ankle weights and push ups e.g 10 kg plate on my back.

I would like to do max pull ups with ankle weights each time.
