arm workout to maintain muscle

Isometric exercise, or static exercise, is exercise that contracts the muscle and holds that contraction for a length of time (versus a dynamic exercise where the muscle contracts and retracts over and over). Isometric exercises are a great, low impact exercise to maintain muscle mass.

These exercises are generally easy, most can be done without equipment (but feel free to add equipment/weights to increase the difficulty and change up your routine), and can be done during your daily life. I like to throw in a set or two of isometric exercises while I'm standing in line or waiting in a waiting room or even doing the dishes. 

This is a list of isometric arm exercises I incorporate throughout my day:

• plank

• push-up hold

• dumbbell curl and hold

• wall push-up hold

• sit on a try and try to lift it while sitting on it

• use 2 fingers to 'lift' the table
