Lizards aren’t working out; their “push-ups” are a kind of body language used to communicate with other animals and cope with their environment.

Quick Scoop

  • Lizards do push ups mainly to send visual signals, not to build muscle.
  • The moves help them defend territory, impress mates, and warn predators to back off.
  • As cold‑blooded animals, the motion can also aid circulation and temperature control a bit.

The Main Reasons Lizards Do Push Ups

1. “This is my turf”

Many male lizards use push‑up displays to mark and defend territory.

  • They often perform them on rocks, walls, or branches where they’re easy to see.
  • The up‑and‑down motion makes them look bigger and more confident, signalling: “I own this spot.”
  • Other males read this as a warning and may back off to avoid a fight.

In some species, rival males basically have a “push‑up contest” to judge who’s stronger without immediately attacking.

2. “Back off, I see you”

Push ups can act as a threat display toward predators, including humans.

  • The lizard shows it’s alert and ready to bolt or defend itself.
  • By lifting and lowering its body, sometimes puffing up, it looks sturdier and more intimidating.
  • This can make a predator rethink attacking, buying the lizard time to escape.

One expert notes that lizards even do these displays toward people when they feel threatened.

3. “Hey, wanna mate?”

Push‑up displays are also lizard flirting and dating behavior.

  • Males use them to show off fitness, strength, and bright colors to nearby females.
  • Some species extend a colorful throat flap (dewlap) as they bob, making the signal even more eye‑catching.
  • The rhythm, speed, and style of the push ups can act like a species‑specific courtship pattern.

Females often choose males whose displays look strong and well‑coordinated, since that suggests good health and good genes.

4. Lizard “language” and body code

Across different species, these push ups form a visual communication system.

  • Signals vary by species: some rely more on dewlap color, others on motion, depending on habitat (dense foliage vs. open rocks).
  • Details like speed, height of each push, and posture change the “message” (aggressive, relaxed, courtship, etc.).
  • It’s a silent code that other lizards instantly recognize, even from a distance.

Scientists often describe it as the reptile version of flexing or waving, but with a very specific meaning in each context.

5. Bonus: Body benefits

Communication is the main purpose, but the motion has physical side effects.

  • Lizards are cold‑blooded, so muscle activity helps keep circulation up and muscles “warmed up” for sprinting or hunting.
  • The movement can improve blood flow, help avoid cramps, and prepare them for quick bursts of speed.
  • Small changes in posture can also change airflow around the body, which may help with cooling or warming slightly.

Some sources even note that when it’s cool, lizards may do more push‑up‑like movements throughout the day, partly to stay limber and responsive.

Different viewpoints & fun nuances

Experts agree on the core idea: push ups are mostly about visual signaling—territory, dominance, and mating.

Where they differ is in emphasis:

  • Some writers highlight the “showing off strength” angle, comparing lizards to people flexing at the gym.
  • Others focus on how the exact pattern and style of the push ups is like a sophisticated, species‑specific code shaped by evolution.
  • A few sources lean more into the physiological benefits (circulation, muscle readiness, temperature tweaks) as useful side effects.

In reality, all these layers can overlap: a single lizard’s push‑up session might simultaneously warn rivals, attract a mate, and keep its body ready for action.

Imagine you’re watching a tiny reptile casting a silent, high‑stakes “status update” with every rep—who it is, how strong it feels, and whether others should come closer or stay away.

Mini FAQ

Do female lizards do push ups too?
In many species, males display more, but females can also use body bobs or push‑up‑like moves for communication, especially in social or territorial contexts.

Is it ever just exercise?
For lizards, there’s no evidence they “work out” the way humans do; the motion is functional communication with useful side benefits, not a fitness routine for its own sake.

Why do they often face one direction while doing it?
They typically aim their display at whoever needs to see it—another lizard, a rival, a predator, or a potential mate.

TL;DR

Lizards do push ups to talk without sound—staking out territory, scaring off threats, and flirting with mates—while also keeping their circulation and muscles in good working shape.
