Recommendation: Verulio Athlete Club is in convenient location and reasonable ($17 per visit). Gold Gym Nagoya Nishiki opened in 2022 with new and great equipment in the entertainment area of Nagoya; Sakae.
Nagoya Kanko Hotel is a great option in Nagoya for fitness travelers. It is an old school comfortable hotel. It says 5-star, but the price is like 4-stars (great value for money!). For fitness travelers, it has a good gym room and hotel guests can use it for free. They even have free-weights up to 20 kg which is rare in hotel gym rooms in Japan. If this is not good enough, you can still walk to a local gym with a day pass: Verulio Athlete Club.
Nikko Style Nagoya is also a good option as it has a decent sized fitness room and hotel guests can use it for free for 24/7. It is a 11 mins walking from Nagoya station. Check out the hotel review and price from here.
If your stay is short in Nagoya, then it would be a good idea to stay close to Nagoya station which is a hub for all transportation in Nagoya. You can visit any tourist spot from this station. The best hotel for fitness travelers is Nagoya Marriott Associa Hotel. It is within the Nagoya station complex and hotel guest can use the gym in the same building.
