Abs and core!
We all love them, Russian twists!
Sit on your butt with your legs slightly bent, feet NOT touching the ground. Lean back until you can feel your abs tighten. Hold you weigh in front of you, and dont forget to keep you shoulders back and eyes up! Rotate you upper body so that your weight reaches past your hip. Now rotade to the other side and repeat! Keep your fett elevated through the whole exercise!
Abs and stability!
Here is your regular plank but with a ball! The ball adds unstability which makes you tighten your core even more!
Legs and butt: Squats! (Plié)
Legs and butt: Squats!
The best leg and butt exercise there is, and it's SO versatile! Do it with your feet together or apart, on your toes or heels down! Do many deep and fast, or do them slowly!
