Fitness accessories for cardio training

Be it protective floor mats, heart rate monitors, weight cuffs or Vario cranks – with the right fitness accessories, your cardio training can be made safer, more effective and more varied.

Why do I need a protective floor mat?

A protective floor mat provides a secure base for your fitness equipment. It protects carpets, wooden or stone floors, provides a non-slip training surface and also reduces noise. Protective floor mats are available in different types and sizes. Puzzle mats like our FINNLO by HAMMER puzzle protective floor mat can be flexibly put together to cover even larger areas.

We offer protective floor mats made of rubber, in walnut look or wood look in the following sizes:

  • 70 x 30 cm
  • 70 x 120 cm
  • 120 x 60 cm
  • 160 x 85 cm
  • 185 x 120 cm
  • 200 x 100 cm
  • 240 x 100 cm

For particularly heavy endurance equipment we recommend our HAMMER professional protective floor mat:

  • 2.5 cm thickness for perfect absorption of sound and vibrations
  • Durable material (EVA)
  • Built-up size 6-piece (L x W x H): 156 x 104 x 2.5 cm
  • Built-up size 2-piece (L x W x H): 104 x 52 x 2.5 cm

Why should I train with a chest strap heart rate monitor?

Hand pulse sensors are just a guide, while a chest strap heart rate monitor is a helpful accessory. With the help of a chest strap heart rate monitor, the heart rate can be read and monitored on every fitness machine with an integrated pulse receiver. The small fitness accessory is the ideal training companion for beginners and advanced users to understand their personal stress and fitness level better and individually adjust their cardio training.

Our chest strap pulse monitors:

  • Large range
  • Accurate heart rate monitoring
  • Uncoded data transmission
  • Individually adjustable size

How heavy are weight cuffs?

Weight cuffs intensify cardio training. You can attach them simply to the wrists or ankles with a Velcro closure. Sand-filled cuffs, such as our HAMMER weight cuffs, adapt to any joint shape.

We offer them in 0.5 kg and 0.75 kg sizes.

Product details:

  • Fits on wrists and ankles
  • Filled with sand
  • Neoprene and lycra for maximum comfort

What are Vario cranks?

Vario cranks are orthopaedic aids for training on an ergometer or home trainer. They are the ideal training accessory after injury, surgery or joint damage. An adjustable crank radius allows crankshaft adjustment with reduced flexion and extension of knee joints.

Our Vario cranks are:

  • Flexibly adjustable from 30–170 mm
  • Suitable for the Varon and Exum models
  • Also suitable for long-term use

Training with the Vario crank can lead to the following results:

  • Strengthening of leg muscles
  • Supporting joint mobilisation
  • Positive effects on the cardiovascular system
