Step Ups are a simple and easy to use item for strengthening the muscles of the legs, thighs, and more. The stepping motion is also useful for improving balance, stamina, and endurance, while being more gentle on your back than other workouts.
All round brilliant thank you very much my little lad loved them.
Good goggles, quality product. It's an old model hence they are cheaper than others from the brand. The glue between the glass and the rubber has changed colour, probably because long time on the shelf.
