Frequently Asked Questions

What muscles does the Concept 2 rower work?

Rowing is a full-body workout. The Concept 2 targets the legs, glutes, core, back, shoulders, and arms in every stroke — making it one of the most efficient cardio machines available.

Is the Concept 2 Rowing Machine good for beginners?

Yes. The Concept 2 rower is beginner-friendly, with smooth resistance and simple operation. The PM5 monitor provides real-time data to help new users track progress and stay motivated.

Can I use conditioning equipment for weight loss?

Yes. Incorporating conditioning exercises into your routine can boost metabolism, burn calories, and aid in fat loss. Combining equipment like rowing machines, sleds, and battle ropes with a balanced diet can be effective for weight management.

What’s the difference between a sled and a prowler?

Both are used for resistance training, but they differ in design and application. Sleds, like the BLK BOX Dog Sled, are typically pulled, focusing on posterior chain development. Prowlers are pushed, emphasising anterior muscles and offering a different resistance challenge.

Which conditioning equipment is best for improving speed and agility?

To enhance speed and agility, consider tools like the BLK BOX Mini Hurdles and BLK BOX Smart Training Hurdles. These are excellent for drills that improve footwork, coordination, and quick directional changes.
