In many cases, my clients are unable to perform traditional strengthening exercises for the lower body due to anterior knee pain or weakness. Beyond loading, using the time under tension principle is a great way to add strength for those who cannot squat, lunge, etc. Below are two great videos of isometric ‘go-to’ exercises that will help improve strength and functional capacity in those who are otherwise limited in their workouts.
I hope you can use these exercises or some variation of them to increase strength and overcome injury and dysfunction.
One of the biggest challenges for clients overcoming knee injuries and surgery is regaining their quadriceps strength and fighting atrophy. This is increasingly so for my clientele on crutches for any extended period of time. It is paramount to use modalities early on in the rehab process such as electrical stimulation and blood flow restriction training to combat atrophy and loss of strength.
Once appropriate, I always move to single limb training to eliminate imbalance and asymmetry. While pistol squats are one of the most effective single leg quadriceps exercises, not all clients can perform this movement. So, in many cases I opt to use a single leg box squat (see video below).
