I don't know how you train in the gym, but since you have gained weight, it may be mainly anaerobic exercise, while jogging is aerobic exercise, which itself is used to consume energy to lose weight. If there is no big change in diet during the period, there is no change in energy intake. Compared with the two, the latter consumes more, so you gain weight.

It is suggested that muscle training should combine aerobic exercise with anaerobic exercise, and then add some high-protein foods to the diet. Meat, fish, milk, beans and eggs are rich in protein, so you can eat more of these foods for three meals. The interval between exercise and diet should be 30 minutes to 1 hour, and the absorption after 30 minutes of exercise is better than usual. If it is inconvenient to eat at ordinary times, you can have some protein powder. You can go to pq'fitness. Be careful not to eat high-calorie food, such as fruit, before going to bed.
