Day 19 has one of my FAVE lower body moves: Lateral Lunges!!

they work the inner AND outer thigh, along with the booty of your bent leg
they stretch the inner thigh of your straight leg
and they challenge your core stability b/c it’s hard AF to keep your posture in check when you’re moving sideways [“laterally”] AND each side of your body is doing all kinds of different stuff [LOL!!]

Here’s what you need to do in order to make sure you’re loading your muscles & not your joints/back so that you’re building strength, not creating tension that could cause you pain:

the foot that steps side is the knee that bends - the other leg stays completely straight
as you step side, hinge your hips: booty back, head forward, spine straight
if you hinge your hips correctly, your upper back shouldn’t round over, nor should your shoulders collapse down in front of your chest
hinging your hips while keeping your abdominals pulled tight also keeps your lower back from arching & your rib cage from “puffing out” excessively
sticking your hips back for the hip hinge will also load the heel of your foot that you stepped on - which is great for engaging the booty
if your knee is poking forward excessively/you feel the majority of your weight shifting into the ball of your foot, stick your butt back farther!!
drive through the heel of your foot [of the knee that’s bent], to initiate standing back up again. Push with power & move with enough speed to give you the momentum to move that foot back beside the other & stand all the way upright again

Here's the demo video so you can see what I'm talking about:

There you go! Time to give it a try!! Get it, Fit Fam!!
