I can't think of any god bar exercises but try
1. V Sits
2. Inclined sit ups.. so your feet on a height, legs bent in 90 degree shape
3. Sit on the edge of a table, feet hanging off the end, place an ankle weight around the ankle,and bring your knee up to the ceiling
4. Lying down (on table), bend one leg, have other leg straight with ankle weight on it, raise your straight leg up only to a comfortable height
(don't let weight touch the table.... make sure knee is straight of leg with weight on it)
