Hey girl! I'm new here too. Micro student. I have spent thousands of dollars on underused gym memberships. :/ Most recently I bought a nice treadmill (three months ago) and have found that I get MUCH more use out of it than my gym memberships. Being a student and a mommy means very little time, so it's easier to squeeze in a short jog when the treadmill is right in the living room staring at me, lol! So far 20 pounds down with a LONG way to go.
If I may, I encourage you to do the free training! I went to one at my old gym and it was with a personal trainer who was very kind and informative. I actually learned a lot about how to use the strength training equipment.
Do you have a friend or family member that might be on board with going with you a few times a week? That has really helped me in the past, when I lived closer to family and had time for friends!
