If you ever worked out at Core Principles you probably noticed doing many single-leg and single-arm movements such as one-arm cable row, single-leg deadlift, box-step up etc. The other day a while working out a client, she asked me what was the point of doing a single-leg squat to a box, when she could just do a bilateral squat using both legs. She thought a regular squat would be more time-efficient and more effective when it comes to hypertrophy and strength development.
I began to explain that though bilateral squats are crucial for lower body strength, unilateral movements are an important part of a well-balanced exercise program, have a ton of benefits and are not to be ignored.
Single leg and arm exercises are imperative when it comes to fitness and overall body health as they help correct muscular imbalances, strengthen stabilizer muscles and connective tissues, improve balance and aid in injury prevention.
