…But I don’t want to spend a lot of money.

Hi folks, after being nudged this way by some other posters I’ve finally decided to start a training log. Thank you for taking the time to read my log - all feedback/encouragement is extremely welcome by the way!
Background:
In short, I used to be pretty active (OCR, parkour and lifting) but things haven’t exactly gone to plan the last couple of years (especially during lockdown) and I’ve found myself in the worst shape of my life. Weight has increased drastically, my knees hurt, I can barely do 6 pushups without getting winded, jogging makes my achilles explode, my lifestyle is attrocious and I’m all round pretty grumpy.
Stats:
- Age: 32
- Height: 176cm
- Weight: 112.7kg
Goals:
—Short term
re-establish some fundamental habits to improve my physical and mental wellbeing. To do this, I initially aim to define and stick to a plan with at least 90% compliance for 4 weeks. A compliant day is only counted if I have not deviated from my plan at all that day. After 4 weeks I intend on reassessing my situation and revisiting my goal definition. I will push myself but only when I feel like it as I want to learn to love the process again.
—Long(er) term
This needs some further work but essentially I would like to drop down to 80kg (I just feel better at that weight) and enter an Spartan Sprint (or Super) in the age group category by end of June 2021.
Training:
I’ll be using a 3 day A-B split (AxBxAxxBxAxBxx) based on the Bondarchuk Complex. I’ll also be working up to adding in some loaded carries (inspired by Dan Johns 5 fundamental movements).
Equipment is quite limited so I’ll have to be creative and manage my expectations. All I have in my flat are a set of dumbbells, a doorway chinup bar, some resistance bands and a kettlebell.

Mobility work: leg swings x10 ea., hip flexor stretch 30s ea., squat stretch 30s, band dislocates x10
