There are eight exercises in all. Seniors can replace jumping jacks with brisk walking or marching, and modify some of the other exercises depending on their endurance levels.
Start warming up in bed with deep breathing exercises and trunk twists. Inhale deeply and expand your lungs as much as you can. Exhale slowly and repeat. For trunk twists, turn your hips and left leg to the right while pulling your upper body back towards the left. You should feel the stretch around the core muscles. Repeat on the other side. You can have a light snack like a slice of toast or a glass of juice before the workout, but if you have a heavy breakfast, wait two hours before exercising.
