I'm new to lifting weights but started after an injury and my physio has been taking me in to use a Smiths machine, among other things.
I started doing lunges and squats with just the bar (not on the machine), and have progressed to lifting 50kg. This week was the first time I did 50kg and my thighs are absolutely spent!
My question is do I wait for them to stop aching so much or do I got straight back in??
