re: Nearing 50 and Hit Rock Bottom

i recommend purchasing plates, a bar, and a squat rack. can likely get the the plates (goin rate seems to be $1/lb) and rack used on fb marketplace or craigslist; buy a new bar online. seems you get what you pay for. i bought the B&R bar from rogue and its great (~$350). learn to squat and deadlift, followed by press. make the compound movements the basis of your training, mix in all of the other stuff when you get bored. but do at least one heavy 3x5 every week of squat, deadlift, and press

edited to add: can get one rubber horse stall pad from tractor supply and lay that down. squat, press and deadlift on that so youre not standing on concrete

im 45yo, that was my path. its changed my whole existence and i recommend it to everyone, men or women
