Cardio and weight loss question

When I started I did nothing (exercise wise) except take walks which started as a 15 min loop around the block and would increase over time. Now I walk/jog for about a 3 mile loop every few days (doing strength training now on opposite days) and it has gotten easier overall except that some days may be harder then other if I'm just feeling tired. Cardio was my best friend when starting to lose weight because it was such an easy thing to do and it eventually just became a routine, the fact that walking was very low impact for me and didn't cause a lot of strain kept my motivation up to keep moving.

Strength training is great to tone your body and lose weight but when I tried to lift weights early on in my journey I found I would get too frustrated with it, or become too sore afterwards and end up taking days off to recover but then be very reluctant to start again. If you are comfortable with cardio then I say keep it up! If you decide to switch up workouts in the future then that would be great as well but I found that when just starting off the best thing I could do to keep exercising regularly was to pick something that I actually enjoyed doing and could just make it a habit, not a chore, to get it done.
