Is my workout plan correct?

Hi!

I've been exercising for over a year and a half. For the first year I used to run regularly 3-4 times a week. For the last half year I've been using ergometer. I had gynecomastia surgery at the begining of August and so I had to stop exercising which eventually led to increase in weight. I want to shed these additional kilos so I prepared a workout plan yet I don't know if it is correct.



The workout plan is simple. I'm going to exercise 5 times a week with days off on Monday and Friday.



Monday: Day off

Tuesday: Ergometer, (10 min of rowing/3 min of rest) x3, tempo: 21 strokes per minute, 2:07/500 metres

Wednesday: Ergometer, (10 min of rowing/3 min of rest) x3, tempo: 21 strokes per minute, 2:07/500 metres

Thursday: 45 minutes of running

Friday: Day Off

Saturday: Ergometer, (10 min of rowing/3 min of rest) x3, tempo: 21 strokes per minute, 2:07/500 metres

Sunday: 45 minutes of running



Because of the month-long break I had to make, rowing is quite challenging to me. Running slightly less but still requires some effort.



Is that workout plan correct? Will it be effective in losing weight?



I would be very grateful if you shared your thoughts on this.





P.S. Something about me:



Age: 20

Height: 178 cm

Weight: 79.1 kg

BMI: 25

Body fat: 15,6%=12,3kg





Thanks in advance,
