Integrated cardio + resistance
Users can walk, incline, decline, and perform resistance movements simultaneously instead of moving between separate cardio and strength stations.
Cal Out Fitness presents VIIT
Strength training in motion.
A patented hybrid cardio and resistance training platform designed to compress conditioning, functional strength, progressive rehab, and performance training into one compact footprint.

The problem
Training environments are crowded, fragmented, and time-intensive.
Fitness facilities, rehab clinics, and performance centers often rely on separate stations for cardio, strength, balance, functional movement, and progressive conditioning. That creates floor-plan pressure, programming complexity, and longer sessions for users who already struggle with time, motivation, or injury limitations.
The product
VIIT combines a treadmill, functional resistance training, and adaptive progression.
Variable Intensity Interval Trainer is designed to let users perform cardiovascular work and strength movements at the same time, with resistance load and programming variables adjusted around the user’s ability, recovery, and training objective.
Progressive training variables
VIIT is built around acute training variables including load, reps, sets, tempo, rest interval, duration, gait speed, and incline/decline.
Compact facility footprint
The goal is to replace multiple training stations with one highly versatile platform for gyms, clinics, and performance spaces.
Software-ready platform
Designed for workout guidance, progress tracking, vitals, recovery metrics, and analytics that can support coaching, rehab, and performance optimization.
Human movement science
Built around work capacity, proprioception, and neuromuscular efficiency.
VIIT is designed to create controlled training stress across the human movement system by pairing locomotion with resistance. The platform can challenge stabilizers, prime movers, heart-rate response, recovery intervals, and movement quality in a single training environment.
Proprioception
Multiplanar movement and changing joint angles stimulate body awareness, coordination, and stabilization.
Time under tension
Variable resistance can extend muscle contraction time while reducing the need for heavy external loading.
Active recovery
Walking-based recovery keeps users moving between resistance efforts, supporting work-capacity development.
Where VIIT fits
One platform for commercial fitness, rehab, and performance.
Independent gyms & boutique studios
Differentiate the facility, increase training density, and offer a premium full-body experience without adding multiple machines.
Physical therapy & sports rehab
Support controlled, progressive movement and lower-impact conditioning for patients returning to function.
Performance & tactical readiness
Blend conditioning, strength, mobility, and functional movement for athletes, tactical users, and high-readiness populations.
Current momentum
From concept to patent-backed product development.
Cal Out Fitness is moving toward product validation with a focus on pilot sites, prototype development, and facility-level evidence around usage, space efficiency, user engagement, and return-on-investment.

Built by a coach, athlete, and trainer who lived the problem.
Steve Lawrence brings direct experience as a former Division I football player, strength and conditioning coach, and certified personal trainer. VIIT grew out of his search for a more efficient training method after years of traditional high-load and high-impact training became harder to sustain.
That background shapes Cal Out Fitness’ focus: practical training science, safer progression, and a system that helps people achieve more work in less time.
Pilot partners wanted
