The first few sessions of anything new can be nerve-wrecking – especially when there’s new lingo, machines and equipment to, quite literally, get to grips with.

Reps, sets, DOMS, plyo – sorting out all the gym jargon can be enough to bring you out in a sweat, even before you’ve pumped your way through a class. Here’s a quick A-Z to get you going like a pro:

Battle ropes – no, you haven’t walked into the ring! Weighted ropes offer full body strength training, and are great for your core and upper body. If you’re new to the gym or working out, it’s worth getting some direction before hitting the ropes.

Bench press – using a weights bench to lift a weighted barbell. Best to use a spotter (explained later).

BLT – another name for Bums, Legs and Tums; these classes concentrate on toning up and strengthening these areas of the body.

Body combat – non-contact martial arts routines set to music in a class format.

Body pump – a fast paced, weights and cardio workout in a studio/class; improves strength and tones your body shape.

Boxfit/Boxercise – non-combat cardio sessions based on boxing moves.

Burpee – a variation on the squat thrust and a mainstay in a BLT class.

Cardio – the shortened version of cardiovascular exercise; meaning exercise that gets your heart pumping strengthening your heart, lungs and blood vessels. Adults should aim for 150 minutes of cardio a week (kids need to do an hour a day). Also called aerobic exercise or CV.

Free weights – you can’t take these home with you! Includes dumbbells, barbells and weight plate machines.

HIIT – stands for High Intensity Interval Training, a form of cardiovascular training that is good for burning fat. HIIT workouts comprise short bursts of high intensity activity, followed by a short rest session or low intensity activity.

Kettles – before you go and get the teabags, this doesn’t refer to the thing that heats your hot water! Kettles, or kettlebells, are a cast iron or steel weight that looks a bit like a cannon ball with a handle.

Plyo – stands for plyometric. These movements (like explosive skipping and vertical jumps) are designed to increase speed and explosiveness, whilst strengthening joints and muscles.

Progression – means anything you progress in; from increasing weights, to how much you can lift, to the time you can do something in. Track your progression to gauge improvement and see what needs more work.

PT – stands for Personal Trainer. PTs usually work one to one with a client and develop bespoke training plans based on their fitness goals. They also offer support and encouragement when things get tough!
