It almost seems like part of the human condition: we like to do things that we already know we are good at doing.
In strength training it boils down to people focusing on muscles that are already strong because it feels good to feel strong. Neglecting those weak muscles is the perfect scenario for injury, because this can create imbalance and torque joints out of alignment as the overly strong muscles dominate motion. To avoid injury you need to find balance.
So here is a reminder of how to work opposing muscle groups:
- If you like to work your quads with the knee extension exercises (straightening) like the leg press, you need to work your hamstrings with leg curls.
- If you like to work your biceps with hammer curls, then you need to work your triceps with some bent over kickbacks that target the back of the arm.
- If you like to work your abs (and if you are not one of them let me tell you there are many people out there who do love to work their abs), then you need to balance all those crunches with some back extension exercises.
