I did a well known beginner's program called starting strength where you add 5 to 10 lbs per week depending on the week doing it once or twice a week. Then I did crossfit for almost a year and went back to starting strength.

By the time I went back to starting strength I was able to start much higher at about 180 and kept increasing from there out, again 5 to 10 lbs a week. The key I feel was consistency. You hardly notice the weight going up if you're consistent.

I am a huge proponent of strength training for general fitness. Please do reach out if you have any questions!
