I like to lift weights but I think I am out of proportion and I am
concerned that I may give myself an injury by having one muscle group
much stronger than its opposite. I am wondering about the ratio of
strength of one muscle versus its opposite muscle. An example is, The
strength of your quadricep should be 33% stronger than your
hamstring...I think that is what it is. These are the muscle groups
that I am looking for proportions between.

1. Bicep vs Tricep
2. Chest(bench) vs back(row)
3. Quadricep vs Hamstring (please confirm)
4. Deltoids vs Latisimus dorsi
5. Latisimus dorsi vs back(row). Should these two muscle groups be
able to pull the same amount of weight?

If there are any others I am very interested to know. Thank you for your help.

If you break a leg, and they put it in a cast.  The musle will shrink.

But if you exercise the opposite leg. the one in the cast does not shrink.

Maybe the body takes care of balancing things out if you let it.
