More fitness enthusiasts are fitting pull-up bars in their homes as they look to avoid expensive gym memberships, it has been noted.
Equipment retailer VIP Home Fitness has seen an increase in the sales of such items from people keen to work out in the comfort of their own homes.
Related products such as fitness mats are also rising in popularity - which the company claims is important if the home environment is to be made a comfortable place to exercise.
But chin-up bars are most popular, with VIP Home Fitness noting a variety of possible reasons for why this is the case.
One suggested driving force behind the trend is the prominence of the bars in fitness and work-out videos and television broadcasts.
Their adaptability to exercises for different parts of the body is also pointed out, promising an all-round routine from a single piece of equipment.
And the ease with which the bars can be fitted into a doorway - and packed away again when the work-out is over - is also noted.
VIP Home Fitness also supplies wall-mountable chin-up bars for customers who are not keen to fit a bar into their doorway - or who are looking for a more permanent option.
