Bring Sally up can be done with air squats, leg lifts, or up down planks. Up down planks are the most difficult, so challenge yourself to see how far you can make through the song.
The Hokey Pokey is done plank style. K-2 will get in a squatting position when it says turn yourself around, while 3-5 will stay in a plank and turn for half a circle. When it doesn't say turn yourself around, hold the plank (no seals or mountain tops!) 3-5 will do a burpee every time it says "that's what it's all about" and at the end when it says "Hokey-Pokey"
This is another great warm-up. Start in the plank position. Do arms, shoulder, head, hips and push-up on "Ahh Macarena". This is a tough one, start with 5 and work your way up to 10. Take breaks as needed and finish the song :)
