I go mostly first thing in the morning (5am) after work so there isn’t any classes otherwise I would. I don’t think I’ll do squats/dead lifts just weight machines.I definitely recommend classes especially any circuit training classes as you get an idea of form with weight training and it seems to be a more all-round exercise.
From personal experience I started with lots of cardio just to improve fitness. Then I started circuit training classes and got a PT for a few sessions who drew up a programme for weight training and cardio and showed me proper technique with regards to squats, deadlifting and bench press.
If you want to do compound lifts like deadlifting and squats I'd recommend a PT even if just for a few sessions just so your technique is right because incorrect form can lead to injuries. It also helps just to have confidence in the weight area.
Personally I prefer doing cardio and weight training as they complement each other I feel. Like when I have stronger calves and legs I feel I can run faster etc. Also just doing one without the other gets boring I think.
Thank you all I’ll have a look at the links above
