Halasana
"No."
Chopper flinched. Sure, he'd expected a little trouble with this, but he'd hoped Zoro would at least think about it for a moment before a rejection. "But it'll be fun! And you'll be able to train without taking off your bandages!"
"I'd hardy call that training, Chopper," Zoro replied, and then focussed his attention back on his enormous dumbbell. Chopper didn't even want to think about the strain on Zoro's wounds, and with every "5564, 5565, 5566..." from the swordsman's lips Chopper was both amazed and horrified that nothing reopened.
"Sure it is!" Chopper protested, flailing his arms in hopes of Zoro looking his way again. Not a chance. "It'll help you maneuver, and it's great for your spine!"
"5713, 5714, 5715..."
Flick.
A tiny, but incredibly irritating, sound entered Zoro's ears, and cigarette smoke his nose. He counted louder. "This isn't a break room," Zoro grumbled.
Sanji either didn't hear him or pretended not to. "You really went through with it?"
Chopper nodded. "I thought asking was worth a try..."
"Don't bother. Zoro acts tough, but he's chicken when it comes to trying something differe-"
WHAM!
Zoro dropped the dumbbell carelessly, Franky was not going to like the state of the floor when he saw it, stood, and turned to Sanji, fuming. Sanji smirked, knowing even if Marimo and him fought for hours, he'd already struck the swordsman's pride more than hard enough.
The next afternoon, all but a few very small weights were shoved into a corner of the training area, replaced with a pair of dusty mats Zoro didn't know they had.
"Okay, first we're going to do a pose called the Downward Dog."
"The what?"
"You put your hands here and... your legs... uh..."
"Like that?"
"Well, sort of."
"You mean you can't even do it?"
"I'm a reindeer!"
Zoro and Chopper's daily yoga sessions didn't last long. Luffy offered to participate in an effort to cheer the defeated reindeer up, but Chopper assured Luffy that he was quite flexible enough already.
