Step 2—Bag It
I have a feeling this season will find you gathering up filled bags and heading from store to store. Utilize all that time spent walking with front-reach shoulder presses.
Start with your arms bent at the elbow, resting on your hips with bags in hand. Slowly reach forward with palms upward. Alternate reaches for 20 repetitions. This will strengthen your shoulders and biceps and help with your upper back posture.
