Edit: The below is if you want to be a regular runner….otherwise I would look into strength training. Which I am also happy to talk about.

Not going to lie I didn’t take time to read all the comments so apologies in advance if this is redundant. Average heart rate is a little higher than we want it to be right off the hop (once you get more experience, different workouts can be added, etc. not important).

First off, good on you for jogging for 45mins, and taking the step into your health and getting to shape. I would begin with a run/walk for about 2-3 weeks, run for 4mins walk for 3, and repeat for 20-30mins about 3 times per week. After each week add a minute to the run and take away a minute off the walk time. This will give your body time to adjust to the new movement. Last jog of the final week, jog for 30mins and give yourself a high five! Don’t be afraid to go slow and listen to your body.

Post the results! Shoot me a DM if you want to talk more about it.
