There are many crazy things that people will do in their search for larger muscles, especially the thighs. Some people will even risk hurting themselves time and time again with strange techniques or unhealthy lifting practices thinking that the risk is worth it to get them ahead. This is unfortunate for two reasons. One, the risks involved can put a lifter out of commission permanently and the risk for injury in general is much higher, and two, after trying every method in the book to grow at a fast rate, once progress seems to be halted, a return to the tried and true methodology of a correct diet and standard pyramid lifting practices usually proves the only true way to advance any further, and could have brought them to where they are without injury to begin with, making the risk a total waste.
Some bodybuilders will take a few warm up reps before an afternoon of power lifting. On the surface this might seem like a good idea, but the fact of the matter is, that being flexible before working out using low weight reps in set amounts LARGER than your power rep cycles instead of the reverse can not only help you avoid injury, but take you further up the weight pyramid in the long run due to healthier elasticity of the muscles due to extensive warming up. It is true that you might have to exert more of your energy during warming up than you wish, but the benefits of doing so far outweigh any growth benefit you might get from risking injury by not doing so.
Start off with high rep, low weight sets, and increase the amount by only a few pounds each set to make sure that you do not exceed the limits of the muscles ability to stretch. The higher the weight, the fewer the reps. Do not rush too fast to high weight, low rep sets, but build gradually.
The other part of a successful power lifting equation is to eat the correct amount of carbohydrates for your goals. If you are not wishing to gain weight mass, and simply maintain competition form, then eating to many carbohydrates can make you have to work harder to maintain without gain. If on the other hand, you are looking to increase bulk, then having too few carbohydrates in your system can starve the muscles, and in order for them to sustain your workout activities, might burn other body resources and result in weight loss instead of muscle addition.
