Hi, I'm Jay McLeod. Today, we're going to discuss what muscles do wrist weights target. Now this depends on what activity is being performed. The reason you should use wrist weights is it adds an extra calorie burning component to whatever activity you are doing whether it's walking, cycling or boxing. Okay now I'm going to show you how to exercise on a treadmill with wrist weights. Okay I already have my treadmill going, now if I want to focus on my forearms and my biceps while I'm walking I'm alternating curls okay, really squeezing at the top, get a nice rhythm going, once again to work your biceps and your forearms. You want to go for about 20 of these as you are walking okay. Now if I want to switch over to the front of my shoulders, my anterior deltoids I'm going to bring my hands right in front of my thighs, okay, I'm going to raise my arms up shoulder height, I'm going to pause for a second and I'm going to drop them back down, raise your arms up shoulder height, pause for a second, drop them back down okay. We're going to repeat, raise your arms up shoulder height, pause for a second, drop back down to really get a good burn in your shoulders. Now, if I want to switch it over to my middle delts okay, and I really want to work those middle fibers, what I'm going to do behind the railing of the treadmill, be very careful doing this okay, you are going to raise your arms up shoulder height, pause and bring them back down, arms up, shoulder height, pause or you can speed up the tempo and you can raise, drop, raise, drop, raise and drop.
