Trying to get home workout equipment so far I got two 10 lb dumbells and two 20 lb dumbells. Also got a pullup bar and 15 lb kettlebell. I want a bench to do workouts off of, I'm not sure if I want a adjustable or a regular flat. My budget is only 100$ and I'm worried the adjustable ones on amazon wont be sturdy at all.

Also I heard resistance bands are very good all around workout. I seen on Amazon for 22$ (HPYGN Resistance Bands Set, Exercise Bands with Handles, Ankle Straps, Door Anchor, Carry Bag, Great for Resistance Training, Physical Therapy, Yoga, Home Workouts 10 to 150lbs) would these be good ??

Any insight would be awesome.

You can usually find a ton of this stuff for pennies on the dollar on craigslist in your local area. I'm not a huge fan of the site and prefer to buy new most of the time, but in this instance it makes good sense.

Yeah I actually been on the lookout but so far no luck. Went to a used store and they wanted 50$ for a 25$ dumbell, and same thing on offer up. I will keep looking though appreciate the advice.
