I found this training (straight-leg push up) really really difficult. I know most men can easily do push-up, but are there any women out there who can do a perfect push-up? Although I had been training myself to lift weights (barbell and dumbell), I found myself not even able to do a single push-up when I initially started to learn it. I'm now able to do some push-up already, up to 15 times for the 1st rep, and the next repetition only 10 times the most. I'm still not satisfied with my push-up, my body posture a little bit out and my arms still not strong enough. How can I improve my push-up and get a nicely toned triceps? 

push up rely alot on core strength also, train hard on plank aka prone bridge will helps
