Hey Rev hope your well dude?
If you are happy with your weight loss so far then i would stick with what you are doing, i spent the majority of my weight loss doing exercise bike and weight training and i found that worked for me. Im not a fan of the rower myself its abit of a love/hate relationship haha but i never do more then 10 mins when i do it.
You could try mixing things up though so you dont get bored and lose interest. Just get out there and go on some walks, x-trainer, bike make a start on the weights and just ease into it and build it up over time. The main thing is to enjoy and have fun with what you are doing.
I also like to do circuit training like the Insanity workout, les mills combat those type of things. It something different and stops things from getting boring.
You are doing awesome so far, listen to what your body tells you and train as hard as you can and you will see the results.
Good luck
