The Ultimate Indoor Sled: How the SB Fitness CT700 Redefines Home Power Training

For athletes focused on functional strength and explosive power, the “sled push” is a non-negotiable exercise. It torches the quads, ignites the glutes, and spikes the heart rate faster than almost any other movement. But for the home gym owner, it presents a logistical nightmare: you need a 20-yard strip of turf and heavy plates, which simply doesn’t fit in a garage or basement.

This limitation has forced a compromise—until now. The SB Fitness Equipment CT700 is effectively ending the need for indoor turf. By combining a heavy-duty slat belt system with variable magnetic resistance, it transforms from a running machine into a stationary power station.

Here is why the CT700 is becoming the secret weapon for hybrid athletes who need to train force production in a zero-footprint environment.

The Mechanics of the “Invisible Sled”

The magic of the CT700 lies in its 8-level resistance lever. On a standard treadmill, the motor does the work. On a basic curved treadmill, you fight friction and gravity. But on the CT700, when you crank the lever to levels 6-8, you are fighting magnetic fields.

This creates a sensation remarkably similar to pushing a loaded Prowler sled on turf. * Constant Tension: Unlike a real sled, which uses momentum once it gets moving, magnetic resistance provides constant, unrelenting drag. There is no “coasting.” Every inch requires maximal effort. * Zero Impact: Sled pushes are concentric-only movements, meaning they don’t have the eccentric (lowering) phase that typically causes muscle soreness and joint wear. This allows you to train at max intensity with a lower risk of injury compared to heavy squatting or sprinting on pavement.

Built to Be Pushed

You cannot perform a max-effort sled push on a lightweight, plastic treadmill; you would push it right through the drywall. This is where the CT700’s commercial pedigree shines.

• The 308 lb Anchor: The unit’s substantial weight serves a functional purpose. It anchors the machine to the floor, providing a stable platform for you to drive against.
• Multi-Grip Handrails: The frame design includes specific horizontal bars that allow for a low, driving body position. This enables you to get your spine parallel to the ground, maximizing leverage and recruitment of the posterior chain.
• Slat Durability: The rubber slat belt is designed to handle the high-torque shear forces generated when your feet dig in to drive the belt backward. Standard thin belts would slip or stretch under this load.

The “Turf-Free” HIIT Workout

One of the greatest advantages of the CT700 is the ability to switch between sprinting and pushing instantly. This allows for “Contrast Training” that is impossible on motorized machines.

Sample Workout: The “Push & Run” * Warm-up: 3 mins walking (Resistance Level 1) * Round 1: 30 sec Sled Push (Resistance Level 8) – Go for max distance. * Transition: Instant (Shift lever to Level 1) * Round 2: 60 sec Sprint/Run (Resistance Level 1) – Focus on high turnover. * Rest: 90 sec walking. * Repeat 5-8 times.

Conclusion: A Powerhouse in a Small Package

The SB Fitness CT700 proves that you don’t need a warehouse-sized gym to build elite athleticism. By integrating high-end magnetic resistance into a robust curved treadmill chassis, it offers a unique solution: a machine that lets you run like a sprinter and push like a linebacker, all within a 6-foot footprint. For the serious functional fitness enthusiast, this is the ultimate efficiency tool.
