8 kgs is fine for many movements, you can even use it instead of a kettle bell for kettle bell swings, you can perform one leg deadlift. might be a bit heavy for most overhead squats and lunges, so you might want to buy a set around 5kg. Because if it is too heavy, you will lose the form, compensate by bending your back in funny ways or putting the pressure on your knees. I see it all the time at the gym
Use you coffee table if it is a strong one or a bench in the park for the step ups.
If you don't want to lose weight, don't do that much cardio. Do as Pipandmum suggests : Go for less, at higher intensity, alternate sprints at 15 or 16 for 30 seconds than 1 min rest, again sprint, 2 min rest, sprint, 3 min rest and last sprint.
Even if your bum is your main focus, when you use bodyweight or dumbbells, you don't isolate a muscle in the same way as when you are on a machine, so for example when I use an overhead 12 kg dumbbells for my lateral criss cross walks, the aim is to work my obliques, but because I am carrying something, my shoulder, arms, backs , bums and legs are working. If you do single arm farmer walk, again you will work big muscle group ,
Go on the athlean website I linked, I get inspiration from the Men videos more than the women, especially as they give more explanations about the proper form.
and check this as well www.menshealth.com/workouts/
I find machines super boring and love experimenting with free weights. If you gyms has Powerplate , see if 2 machines are close enough for you to use two at the same time, with one foot on each for your sumo or lie squats and lunges.
The bum will also benefit if you work your abs and shoulders because you will walk and stand straighter giving your bum an immediate lift!
And for the add/adb-uctor machines . If you are sitting on your butt, you are not exercising it!
For the inner tights, use a band, for the outer tights, do clams with a small plate.
Have fun!!
