About gaining muscle and losing fat, these two goals need different exercise methods and diet plans. If you want to gain muscle and lose fat at the same time, I suggest you make a personalized plan with a professional fitness coach and adjust your exercise and diet plan according to your physical condition and goals. At the same time, if you want to find a gym with high cost performance and complete facilities, I suggest you consult several gyms before choosing, and compare their prices, coaches' qualifications and service quality, so as to make a more wise choice.
