Action drama with physically strong leads

Maybe:

• Tale of the Nine-Tailed 1938
• The Uncanny Counter (In the beginning ML received training from FL)

• Military Prosecutor Doberman
• Alice, the Final Weapon
• Happiness
• Moving

+ flower of Evil
+ LUCA => BUT drop this drama on episode 8. The drama is absolutely amazing in the first 8 episodes and you will have a somewhat concluding end if you do that. But the last 4 episodes? I have no idea what happened to the writers because the drama goes from a solid 10++ to a -1. These episodes were a joke. Thus, drop at 8 onwards. 

My Name - kinda fits all you look for. All main characters are strong, FL hides her identity
Kill It 
Lawless Lawyer
Stealth Walker - Chinese drama,  both are strong, FL is undercover thus secret identity.
Vagabond  - FL is somewhat having a secret identity

 emeraldarrows:

• The Legends - they're a battle couple when fighting side by side, and I'd say pretty equally matched when fighting each other. FL is hiding her identity for part of the drama (her spirit is sharing the body with a more fragile girl).
• Flower of Evil (both are strong, no real physical fight but FL does pull ML off a guy he's about to kill) 
• L.U.C.A.: The Beginning (possibly? FL and ML have a fight and she's quite strong but he does win it)

Thank you for the reply.

I have an idea about the dramas mentioned.

Wonderland of love is great! Their first fight scene is amazing

City Hunter - It's not a secret that the FL is strong, because she's a cop and a presidential bodyguard. But she and the hidden identity ML do spar once (or twice?) in training. He's stronger than her, but then, he was raised by a revenge obsessed military man turned drug lord in the Golden Triangle.

Bromance - She's a skilled martial artist who lives as a man because of humorous plot reasons. He's a gang lord with a heart of gold. They meet when he's alone and ambushed  by a large number of fighters, and she joins in on his side. They fight as equals and insta-collaborators. So in a way, she's a surprise to him. I seem to believe there are some other skirmishes, although mostly this is an adorable, goofy romcom with extra cuteness on top. You'd appreciate the very final scene (after the final credits - don't let anyone spoil it for you).

Guardians of the Ancient Oath - It's not a spoiler to say that the main characters all transform into supernatural beings - the dual character names in the description let you know what to expect. But describing the exact nature of the changes for the younger couple with a (low key) love line would be very spoiler-y. So I'll just say that there's a lot of magical combat power and possession in this drama, and there's some mystery about the main female lead, who eventually wields great power.

The Long Ballad - Li Changge and Ashile Sun don't fight hand to hand against each other, but they meet under assumed identities. And they are both military leaders, allied with groups in conflict with each other. They have a memorable physical contest in the first episode, as opposing team members in a game of ancient soccer (with wire fu) called Cuju.
