I do bootcamps and strength classes all the time. I have this set and am pretty happy with it. It's 5, 10, 15, 20 & 25 lbs. Sometimes I feel like I could benefit from an 8 or 12 lb set, but such is life. Also I paid just $230 for it in 2018, so it was a relative bargain compared to today's prices. :/
