Neglecting to train opposing muscle groups can result in muscular imbalances, where certain muscles become stronger and tighter while others become weaker and lengthened. This can lead to issues such as poor posture, decreased joint stability, and an increased risk of injury during physical activities. It is important to maintain balance in muscle strength and flexibility to support overall joint health and movement patterns.
