Upper Body Strength
Not feeling as strong as you would like? Most people who do not participate in balanced training programs (especially women) have more strength in their lower bodies due to the type of activities they choose for exercise. For example, walking, jogging, biking, or using the elliptical machine. These types of exercises use mainly lower body muscles, so the upper body muscles are not being strengthened equally.
To balance out your body strength try incorporating weights, bands, military training (i.e., push-ups and pull-ups), or even yoga into your routine to engage the upper body muscles.
If you choose to use weights or bands be sure to hit all the major muscle groups of the upper body – shoulders, biceps, triceps, back, chest, and perhaps rotator cuffs.
Push-ups, pull-ups, and many yoga poses, such as plank or crow, engage all of the upper body muscles.
Balance out your workout and begin to notice your increased strength!

I have that problem! When I use machines for my legs I can push, like, 150lbs or something ridiculous, but my arms are around 50.
That’s why we’re balancing you at yoga!!
