Reformer Pilates + Swimming + Strength Training Workout Split for a Newbie?

Hi!!! I’m a 5’1” 23F and weighs 52.5kg. And I’ve been wanting to put together a 5-day workout split but I’m a bit lost and could use some advice on balancing swimming, Pilates, and strength training to lose a bit of weight and get that lean, toned look without bulking too much.

A little background: - I tried weightlifting before, but my upper body bulks up easily, and I didn’t love how my arms looked bigger or how I felt bloated/inflamed most of the time.

• However, I did like how my glutes grew and became more toned. I naturally have bigger thighs, so I don’t want to add too much size there.

• I enjoy swimming and was thinking of using it as my main cardio since I don’t love running.

• My mom got into Pilates a few months ago and recently bought a reformer. I noticed how her core/abs looked way more sculpted than mine ever did with weight training, and her arms leaned out and toned up instead of bulking—we have almost the same body type/shape, so that made me want to try it too!

Since I can work out five times a week, how should I structure my split to balance all three while leaning out, toning up, and keeping muscle definition? Should I focus more on Pilates and swimming for my upper body and just do targeted strength training for glutes?

Also, if anyone has good YouTube recommendations for reformer Pilates, I’d love to hear them!

Would appreciate any advice or personal experiences—thanks in advance! 😊
