Hemsworth was recently spotted looking seriously jacked up with fans noticeably impressed. But his latest clip shows nothing has changed for the larrikin despite his new sizeable frame.
If you're new to the sled push, it's a great exercise that will make your legs shake.
However, there are a few things to keep in mind: when it comes to form, keep your hips below your shoulders and don't let your butt get too high. Also ensure your abs are tight while slightly tensing your shoulder blades.
