TAMPA, Fla. -- Beware, American League batters: Aroldis Chapman is taking advantage of this additional downtime to take the old Spring Training stand-by -- ¡°best shape of my life¡± -- to another level.

In a workout video recently posted to Instagram, the Yankees' closer demonstrated how he pumps iron in the gym of his Miami-area home, then he put his legs to work by logging steps on a StairMaster and pedaling on a stationary bicycle.

If fans at home are looking for a way to spice up their exercise routines, they could do far worse than to replicate the battle-tested maneuvers that have helped Chapman regularly light up radar guns in the triple digits, awing fans and teammates alike.

? How MLB players are staying fit during shutdown

¡°I see this guy every day and there's still days he comes in and I¡¯m like, ¡®He looks especially jacked today,¡¯¡± Yankees reliever Zack Britton said recently on SiriusXM¡¯s MLB Network Radio channel. ¡°He's huge. He is a physical specimen. I've been playing with him for a while now and I'm still blown away with some pictures and stuff like that.

¡°We always give him a hard time, but he's the only guy I know that can be that jacked and still maintain range of motion in his shoulder. He's so flexible and his arm is a whip. I mean, it's unbelievable. He's just one of those guys. That's a freak of nature physical specimen. It's that rare breed and obviously that's why he throws 105 [mph].¡±
