I have talked to others who hate training legs. The main reason is that whenever you train your legs you also train your heart, lungs and entire body. Hence, it’s very difficult! We humans hate to do what’s difficult don’t we?
Here is one tip that might help: Since you have not been training your legs simply begin a program of once per week leg training until you can adjust your mind and body to the rigors of leg training. Anyone can do something if it’s only once per week. Right?
Let’s say you set aside Wednesday for example. Each Wednesday you increase your poundages and or sets, reps (depending on your program) until you are having one heck of a hard leg training session. Since it’s only once per week you will be able to hang in there and complete it. You might also set a time limit of say 30 minutes. Now we are only talking about 30 minutes once per week. See my point?
Once you get used to training legs over an 6 to 8 week period I Suggest that you ease up on the intensity and add one more leg training day per week. This too will not seem so bad because you are going to cut way back on the intensity level as sort of a reward for moving to twice per week leg training.
This is simply a way to move in the right direction. There are others of course.
Give it a try, you have nothing to lose but your skinny legs!
