This by far is the number one reason why people get injured. Trying to perform an exercise that you are not proficient in or using too much weight is commonly seen in the weight room. Many of us may think we are strong enough, fit enough and smart enough to know we have the right technique but oftentimes I see people trying to move ahead to fast. The “I want it now” and “I am ready to push it too the limits” attitude has it’s pitfalls.
If you are performing an advanced exercise, say the deadlift or power clean, make sure you are using proper form and move up in weight slowly. You also may need to use a regressed movement pattern in order to master that exercise before you even do it. Also watch the volume of your workout. Quality will always trump quantity.
