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?

Observation from my own workout:
Doing some pressing movements like bench press & overhead press (dumbbells or barbells) helps.

As the weights in the presses increase, I normally would be able to do more push ups (as long as I don't stop training in push ups).

Might want to check out hundredpushups.com too!

u need to build strength on your arm; and ways that i know r to practice yoga (tis will take a long time) or lift dumb bells

Actually it is the other way around. Your ability to do more pushups results in more weight used during presses, not the other way around.

Anyway easily the best way to improve pushups is by:

1) Identify the maximum amount of pushups you can do (i.e 15)
2) Divide it by 2 (so you get 7)
3) Everyday constantly do sets of 7. You can do one set every hour maybe, or every time you go to the bathroom etc.
4) Add one rep every 2 weeks.

My client at 48 years old, does straight legged push-ups. For 3 repetitions. Eccentric push-ups can help.
As for my client, she did plenty of dumbbell swings and dumbbell clean and push presses along with some wheelbarrows.

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

Of cause Many women can do straight leg push up duhh!! Do more Tricep Dips, Lying Dumbbell Extensions, Reverse Grip Pushdowns , Dumbbell Kickbacks, Side plank, reverse plank, front plank. Tricep pushup would be my favourite.

I can't see a single reason to actually do the plank honestly. The lack of a movement makes me find it an extremely boring exercise. I know David Beckham uses it, but I personally, see no benefit in wasting my time in a plank position. UNLESS, you're using it with load. with load, fair enough then it's of good purpose.

Hanging leg raises, glute ham raises, back extensions with weights, reverse extensions, dumbbell swings, front squats, quarter front squats with back squat max, these are workouts that should be incorporated to get a strong core. It's taxing both isometrically and dynamically.
