Maintaining Lower Body Strength After 50: Exercises and Research

Did you know that lower-body strength can decline by as much as 5% per year after the age of 50? While this statistic may sound alarming, it doesn’t necessarily mean immediate changes or a drastic overhaul of your exercise routine. It highlights the importance of being mindful of maintaining healthy muscle and functional strength as we age. This can be achieved through a combination of resistance training, strength training, and calisthenics.

The Importance of Strength Training

Research indicates that fitness begins to decline around age 35, making it never too early or too late to prioritize strength training. Maintaining muscle mass is crucial for staying strong, independent, and active. A lower body strength routine can support mitigate age-related muscle loss and prevent injuries.

Research on Age-Related Strength Decline

A study published in the Journal of Strength and Conditioning Research investigated leg strength decline in adults aged 50-80. The research found a significant loss of isometric knee extension (approximately 5% per year) and knee flexion (roughly 3.6% per year) in both men and women [1]. Researchers suggest that resistance training is essential for older adults, and endurance exercise alone may not be sufficient to prevent muscle strength loss. Muscle mass loss, known as sarcopenia, can occur at a rate of up to 1% per year after 50 in sedentary adults, potentially leading to decreased strength, metabolic rate, increased risk of falls and fractures, and loss of independence [1].

Three Exercises to Maintain Lower Body Strength

Here are three exercises to help build and maintain lower body strength:

1. Supported Pistol Squats

Supported pistol squats can be performed by standing on one leg, extending the other leg forward, and lowering your butt onto a box, reformer bed, chair, or bench. This exercise develops pistol squat technique and builds the necessary prerequisites for a full pistol squat. It also isolates one leg at a time, mimicking forceful leg movements used in daily activities like jumping, climbing, walking, or running. This unilateral movement improves balance, coordination, stability, and helps identify and address any strength or range of motion limitations [2].

2. Reverse Lunges with Arm Raise

Performing reverse lunges on a reformer (or using sliders, a towel, or dishcloth) keeps muscles under tension throughout the entire movement. As you lunge, lifting your arms into the air further tests balance and stability, engaging the upper body. Maintain a straight back leg with a soft knee bend, focusing on a stretch in the hip flexors and working the gluteal muscles in the standing leg. Adding weight can further progress this exercise [2].

3. Side Lunge ‘Slide’

Using a reformer (or simply performing the movement without) targets the inner thighs (adductors), glutes, quads, hamstrings, hips, and core. Drive one leg outward and back with control, engaging the inner thighs to pull the reformer bed (or your body) back in. Focus on slow, controlled movements and a full range of motion. Remember to switch sides. This exercise creates constant tension in the legs, known as time under tension, leading to a significant burn in the legs, glutes, and core [2].

Trainer Tips

These exercises can be incorporated into a circuit with 45 seconds of work followed by 15 seconds of rest for 4-5 rounds. Alternatively, perform 8-12 reps per leg per exercise for 3-4 sets, with 30-60 seconds of rest between sets. Minimize rest between exercises [2].
