I've moved long distance twice now. You're trying to move too much stuff.
Ditch the exercise equipment. Buy it used when you get to the other end, as you need it. In the meantime, your exercise is moving, running and walking. Trust me, you'll get plenty.
Also really go through everything and declutter. Hobby stuff, clothing, books, kitchen, etc. If you don't use it now, you don't need it. If you're thinking you need to replace it due to age/wear/not working/whatever, then don't move it. Don't move food or cleaning supplies - use up what you can and give the rest away. Plenty of shelters, food bank, etc could use that stuff.
You don't say, but if you have kids, then you can probably purge a TON of outgrown stuff or plain junk. Don't move that stuff. If you have pets, really go through whatever stuff you have for them - I didn't move most of the cat furniture and went through the toys & beds. Tossed a bunch of junk.
My last long distance move, I took a full car load of food, cleaning supplies, misc stuff to a friend's house. She was older and lived in a retirement community. There were a number of people there on a fixed income, and she'd agreed to help distribute that stuff to whomever needed it. Food banks won't take opened food, but since she was involved and could tell people it came from a clean house, people were willing and happy to use it up. Sold or donated 60% of my books (I still moved 2 full bookcases). Purged clothes I wasn't wearing anyway. Anything that came from IKEA was disposed of in someway, either sold or donated.
To give you some sense of how much is possible: my last move, I sold or donated 80% of my furniture and 50% of the rest. You're worried about "losing money" - its a sunk cost. You're just going to throw more money into moving something that has very little resale value already. Realistically, it's cheaper in almost all cases to buy new stuff on the other end of a long distance move.
Once you've done the purge or at least figured it out, then you'll know roughly how much you need to move. I used less than a third of a moving van, so could use one of the partial fill services. The less you have, the cheaper it is to move and the more options you have.
Also, when you're packing stuff, clean it first. It'll be much easier on the other end if you don't need to worry about cleaning anything before you put it away!
