Q. Hey Fitz! How should one proceed if the dominant-hand side is significantly stronger than the other? I was using Nautilus-type equipment, but felt like my right side was doing all the work, so I've switched over to free weights. Dumbbells in particular. I'm worried about staying symmetrical. Thanks, Ann.

A. Hi Ann. Great question. I see this a lot, and the first thing for you to realize is that most people are a bit stronger on one side. Strangely, lots of people are stronger on their non-dominant side too. Sounds odd, but it seems a lot of people carry the groceries with their non-dominant hand, so they can perform the fine motor skills with their dominant hand. I'm a righty, so I carry my kids on the left and unlock doors with the right. That has lead to my left side becoming stronger.

First thing you should analyze is whether you have a lifestyle reason for your disparity in strength, or if you have some sort of medical issue happening. It's possible an injury has lead you to favor one side. Think about it, and if it could be medical or if the difference in strength on each side is drastic visit a doctor. You may simply be missing a medical condition.

If there isn't one and you're just mildly weaker on one side.......you're already on the right track. Stick with dumbbells. Work towards lifting the identical weight on both sides, and then always do a few extra reps on your weaker side. The extra work will help the weaker side catch up. Let me know how it goes Ann! Fitz

Yo. Fitzie! I've been running a bunch to lose weight, but can no longer bare to do so because of chafing in my upper thigh area. Any suggestions? I'm dying here. Jax

Ouch Jax! Chafing hurts, and boy are you going to love me in a few days. I have some clients with the identical issue and they've all had major success with a product called Body Glide. It goes on like a stick of deodorant and apparently takes away the chafe. It works on legs, arms, ribs, feet, and anywhere else your body is being rubbed. I just saw a stick of it at The Sports Authority and I think it only cost about $6.50. Not bad for a product that provides so much relief. Aye? Get yourself a stick Jaxie and we'll go for a run together!

Punches & Kicks,

Fitz
