Bb, pedals, crank bolt are the likely culprits

That sounds like your bottom bracket so id check it for excessive play mate ..

Or pedals, or cranks, or seatpost or headset, or ...

If it's a square taper, check the bolt bolding the cranks to the BB is tight, if the crank is loose it's probably wrecked already.
