Looking back on when you first started lifting/exercising, what were some dumb things you did?

not getting on a proper program quicker. Other than that, no. The internet exists, there is no room for failure when you have all the information in the world right on your cumstained computer.

squat and deadlift

quarter-half repping squats/bench for about 2 years. the friend that "taught" me how to lift let me do this, and I never knew this was wrong until I found Veeky Forums and youtube. I wasted so much time being a half-shitter :c

caring about my 1rm

doing heavy singles

not doing enough cardio

not warming up

-1500kcal deficiet, only 1 rest day a week, I lost 20kg in a short amount of time but had little muscle development

I didn't get on a proper program, and didn't do squats or deadlifts....

You didn't do them? Or you did them?

What do you do to warm up?

>3 sets, 12, 12, 10

Thought the 12, 12, 10 was one set.
Did 34 rep sets of bicep curls for 4 months. 5 years later arms still small.

10-15 mins of light cardio is a good general purpose warmup. or a lot of very light reps of your main lift. e.g., for my leg day warmup i'll alternate sets of 20 goblet squats with 35lbs with box jumps, and do 5 or 6 rounds of that.
