If your goal is mainly weight loss, and a slim toned ( hate that word) build, this is where I like putting clients on Body weight circuits.
So if you can pick 3-6 body weight moves, and mix this with a cardio machine for a set distance, put it all togather in one circuit, then do the circuit, say 5 times. Time yourself, and work hard at beating this time next time your in the gym. I’ve witnessed lots of sucess with this type of program for the goals you listed.
Here’s my favorite, but you can play around with different cardio machines, and different exercises, to keep it fun
1/2 mile on eliptycal—20 goblt squats–20 astst dips----20astst pull ups—20 KB swings, rest repeat 5 times, including the eliptycal each time through the crcuit ! Record how long it takes to complete 5 circuits.
I have all kinds of variations on this, but this is a good example. For weight loss I like my clients to try and do this every other day. Over time you should be able to get this down around 30 min, but the first couple times don’t rush, just get used to doing it, and learning the lifts.
Also, if you still want to lift weights, you could pick 1-2 moves before you do the circuit, like bench or squat for your 5x5 or whatever, but then end with the circuit. I can promise you if you put cosistant effort into the above circuit, in 3mths you won’t lok like the same person. You need to wake your body up, and walking endlessly on a tread mill won’t do it. A circuit will speed up yopur metabolisim, build muscle, and burn calories. Good luck
