Routines & Rest Days - What's Your Best Advice?

Here's the deal ... I've been told I'm not giving myself the appropriate rest days. I've also been told I need to switch up my routine to re-start my weight loss as I've stalled. I get it, I don't necessarily disagree ... but I'm stuck for inspiration.

Here's what I do .... I go to the gym every work day of the week with the weekend as rest days. I'm limited to exercise that has no impact (back & knee problems) and hate swimming. Consider that no music = no interest. I am not so much a creature of habit so much as a monster of habit and I struggle to do things differently on the fly.

Definitely found that I'm a morning gym person (not lunch or eve) and can commit to 90 minutes a day.

Here's what I won't do ... I've always had big muscely thighs and calves (sport in youth) and the same for my upper arms so I'm really reluctant to do much on weights unless I can be sure they won't bulk me out even more.

Routine ....
Monday - Spinning Class 45 mins
Tuesday - PowerPlates 15 mins, HIIT on Eliptical for 75
Wednesday - Same
Thursday - Same
Friday - Spinning Class 45 mins
Sat & Sun - Rest.

If I oversleep my 5:15am alarm on Friday (which I often do) then I'll go to Spinning on Saturday mornings instead. I don't love this as it's the only day I really get to catch up on the lost sleep from 5:15 morning wake ups.

Creativity is hugely welcome. I'll put in the effort but I have 25lbs to go after a year and I'm only half way.

Suggestions, advice, recommendations, guesses ... I'll take whatever anyone has to offer!
