Kettle bells are old school but very effective for core strength.
Here is my homemade power rack I built out of 2"X4" lumber in my basement years ago during the lean years.Still use it today.
I have a total of a little over 400 lbs in plates. Used a ez curl bar up high for a chinup bar, bicycle bars for extra grips. Safety spot rests for heavy bench presses, decline to incline bench. Used 2"X4" inside measurement steel tubing that slides up and down uprights locked with a 1/2" carriage bolt at different holes for bench presses, shoulder presses.
I workout on a 3 day routine. Day 1- back, biceps. Day 2- shoulders, chest and triceps. Day 3-deadlifts. Every day abs [hanging knee raise, crunches]. Every day treadmill.
