Stepping into the iron jungle for the first time can be a daunting experience for gym newcomers, especially when you’re already suffering from gymtimidation. But having a solid, yet simple workout plan to follow can can help boost your confidence. That’s why we asked Jenni Tardiff, Master Trainer at The Gym Group, to come up with the ultimate full-body gym workout for beginners that will help turn you into a lean mean, muscle-strength machine.
“This workout is great for beginners as it moves through both machine-based and dumbbell exercises that target the whole body,” says Tardiff. “Machines are great for beginners as they can support proper form while building strength.”
Research also shows that machine-based exercises can build just as much strength and muscle as using free weights, like dumbbells. However, this workout uses a mixture of both.
How to do Tardiff's workout
With no distractions, you should be able to blast your way through this workout in 35-40 minutes. If you don’t know how to use the machines for the exercises below, don’t panic— most of them will have instructions on the side, or just ask an instructor (we know this can feel intimidating, but it’s what they’re there for!).
To warm up, Tardiff suggests spending five to 10 minutes on a cardio machine of your choice, such as the treadmill, exercise bike, or rower to wake up your muscles and get blood flowing. Then do 10 bodyweight squats, 10 bodyweight lunges (five on each leg), and 30 seconds of arm circles, forwards and backwards. Make sure you have your gym water bottle to hand to sip on throughout to replace lost fluid and help muscle function. Most importantly, enjoy the workout!
