Another great core exercise you can do in the comfort of your home or a gym.

The first exercise is the Plank/Prone Bridge. (core) Hold for 30s-1m

Second exercise is the plank up. (core, chest, shoulders, triceps) Perform 6-10 per arm

Third exercise are the knee ins. (core - obliques, shoulders, chest, & triceps) 8-12 per knee

I recommend doing these exercises every other day for optimal results.
