Stand on your left leg, holding a 5- to 15-pound kettlebell or dumbbell in your left hand, and lift your right knee straight up. Lunge directly to your right, keeping your right knee directly above your foot and extending straight down in front of you. For perfect form, extend your booty and keep your left leg straight the entire time. Firmly push off your right foot to return to starting position, then repeat 15 times. Complete 15 reps on each side.
Just repinning...I used to HATE these but they work! With your back against a wall, hold a medicine ball, or a kettle bell, with both hands in front of your chest and lower into a squat (a). Keeping your hips steady, twist to the left and reach the ball toward the wall (b). Return to centre. That's one rep. Repeat on the other side. Move back and forth at a slow, controlled pace for 20 total reps. Quick tip: Make it harder by fully extending your arms instead of bending your elbows..
