MAPS MODS are workout programs designed specifically for individual “hard to develop” body parts. With consistent training and good diet, you should experience good results and visible progress, HOWEVER you might also notice “uneven” results. Most of your body may progress well, but you may also have one or two “stubborn” body parts that seem to lag behind. This can be EXTREMELY frustrating, but don’t freak out. It’s actually pretty common to have a body part that doesn’t seem to respond like the rest of your body. In fact, it’s so common that we decided to design body part specific programs that are engineered to get even the most unresponsive body part to change, grow, sculpt and become more defined. The best part is that they are easy to use. Just use our MAPS Hamstrings MOD program in place of the current exercises you are doing for your hamstrings. If the rest of your body was doing fine before, keep the rest of your workout the same. Just replace your hamstrings routine that isn’t working and watch how well your hamstrings respond.
