Lehner Fitness in Chula Vista's Eastlake district provides personal training and nutrition coaching from a studio at 821 Kuhn Drive, Suite 106, in the same business park that houses GreenSpeed Training Facility at Suite 102. The programming pairs customized workout plans with dietary analysis and calorie-tracking protocols, addressing body-composition goals through both exercise prescription and macronutrient management. Published guidance from the studio covers topics such as calorie-burn accuracy across different cardio machines and fall-prevention strength work for older adults, reflecting a training scope that spans athletic performance through geriatric mobility. The Eastlake location on Kuhn Drive places the studio in the same Harold Place–Kuhn Drive fitness corridor that includes Reformer-based flexibility work at Pilates of Eastlake. Sessions integrate resistance programming with nutrition periodization cycles, adjusting protein intake and caloric targets to match training-load phases across cutting, maintenance, and muscle-building blocks.
