Are there any cardio exercises for seniors that mainly use the arms and do not involve walking, biking, using a treadmill, or swimming?

Hold your hand up for muscle power:
Intensifying strength with small weights or rubber bands helps improve muscles (bodybuilding) and muscle power. While your feet are soft on the floor, sit or stand, and then keep weights at a vertical distance from the floor to where your shoulder ends and your arms start. Your palms should be in an anatomical position, then raise the weight over your head. Another helpful exercise for muscle power consists of lifting your arms up and out to the side – keep the weight beside yourself. Palms situated on the inside, bring your arm up to your sides- and to front dumbbell movement- keep the weight beside yourself, palms should be down and move up your arms to shoulder height. Repeat this for three sets of 10 reps.
