I've got a fun little leg workouts for y'all this Wednesday! This is one that you can do just using body weight, so no equipment required. It mixes some plyometrics (explosive movements) in with some body weight resistance moves. If you want more of a challenge, you can add dumbbells to exercises 3-6. I don't recommend using them on plyo moves, too dangerous and unnecessary anyway.
REPEAT 4 X
On any lower body movement, squats and lunges in particular, always be sure that at the bottom of the movement, if you look down at your knees, you can see your big toe over your knee. If not, you're shifting forward and putting your knees at risk for an injury, focus on shifting back until you can see that big toe. Mirrors are very helpful when it comes to checking your form, even if you're working out at home.
Also, skate jumps are less known than the other moves, but you are basically doing lateral lunges with a jump to get you from one side to the other. When in doubt, Youtube it ;)
