I was one of "those guys" who always had to train at a gym. But now its all home gym for me. Love it.
But as you mentioned your motivation is down and you haven't been training much. "Dude" you just purchased your first house!! This can have a flow on effect, what with all the documents you have to sign, meeting bank managers, sign this, sign that, stress, uncertainty ...of course your motivation can be screwed up.
Once your all settled and moved in things will become more routine.
Congrats on your purchase. Home is where the heart is.....and when the training begins!
Cheers,
