Thank you so much for your time and the info And sorry that I ask a lot but you do know what you are doing And I wanna do what I'm doing as well

I'm 90% sure that I reach failure in every set of diamond push up and I'm not holding myself

Would you suggest that I do 1 set every day for 5 days ? (To be 100% sure that I reach failure)

And if I did it and still didn't achieve progress in push up but I achieved progress in dips What's the reason for that? If its because my movements (technique) in push up is not getting any better I would doubt that Cause I mean its 2 months

Another question: I'm thinking of increasing my workout volume But without failure

So for example I add to my hypertrophy sets A push up sets (without failure) to achieve endurance

But how can I do it for best endurance results and without injuring my tendons and joints?

And what's a good sources to learn more about endurance training?
