Science Fitness Personal Training is a private studio gym at 4228 Adams Avenue in Kensington, San Diego, where trainer Mike Jensen runs one-on-one sessions that rotate between kickboxing, free-weight strength circuits, machine-based hypertrophy work, and martial-arts conditioning across boxing, Jeet Kune Do, and Jiu Jitsu. The 92116 studio operates by appointment, giving each client uninterrupted access to the full floor without the equipment-sharing delays of a commercial gym. Jensen alternates modalities week to week, pairing a boxing round one session with a barbell-and-dumbbell strength protocol the next, a programming rhythm designed to prevent plateau while maintaining progressive overload. The combat-sport emphasis connects Jensen's training methodology to the competitive fencing and theatrical swordplay tradition at Cabrillo Academy of the Sword, where athletes on Adams Avenue build the same rotational power and fast-twitch recruitment patterns that underpin striking and grappling disciplines. Jensen also integrates yoga flows and flexibility drills into his programming, addressing the mobility deficits that accumulate from heavy resistance work and repetitive striking patterns. The studio sits on the Kensington stretch of Adams Avenue between Biona Drive and Vista Street, sharing the block with the Clan Rince Irish Dance studio and the cafes that anchor the Kensington commercial strip near the Kensington-Normal Heights Branch Library. Clients working through chronic joint or spinal issues pair their training cycles with alignment-focused care at Health Vibes Alternative Therapy in Normal Heights, creating a strength-plus-recovery loop that addresses both load capacity and structural balance. The private-session format accommodates ages and conditions from active seniors rebuilding strength after cardiac diagnoses to competitive athletes refining sport-specific power output across the gym kensington corridor.
