Regular gym goers will already be familiar with these fitness trends - but they are set to be even bigger next year.
One of the fastest-growing trends to hit the UK over the last few years is HIIT training, with fitness experts including Joe Wicks, The Body Coach, regularly sharing exercise routines focused on this method.
HIIT - or high-intensity interval training - is a form of cardiovascular exercise with short periods of anaerobic training with less intense recovery periods until you are too exhausted to continue.
The programming developed within the HIIT concept is becoming more comprehensive and is set to make an even bigger impact in 2020.
While these are not new, they are set to get even bigger in 2020.
Steven Virtue, fitness experience manager at Totally Fitness, said: "Fitness apps are becoming a popular training tool for gym-goers at all levels, as they have been specifically designed to make the fitness experience easier.
"Users can do all sorts, including book classes, monitor workouts and gain specific advice and guidance to help achieve their goals using app technology.
"The continuing rise of the digital age will see more usage of fitness apps in 2020, covering topics from training, nutrition, lifestyle and more.
"With a wide range of exercise videos, workout tips and supporting information available, there is something to support everyone’s fitness routine."
Virtual fitness equipment
Steven Virtue said: "Virtual classes have been extremely popular in 2019, with the virtual concept set to develop even further next year.
"Machine-based training can often become tedious, so by including a virtual element into the equipment, the user receives an assisted approach to their exercise training and stay focused."
Functional training rigs
Growing demand and improvements in materials mean that functional training rigs (think climbing frame for adults) are becoming more accessible for 2020 with improved designs to meet the training needs of its user.
Available in a range of sizes, functional training rigs bring together a variety of exercises and allow the user to weight train, bodyweight train and stretch all in one space.
Steven Virtue added: "Rigs are becoming more affordable for people to use at home, so it’s easier to continue exercising between gym sessions."
