Did my first Pilates reformer class, and have it scheduled for twice a week. Anyone here combining Pilates+strength training, what’s your split? :)

Help this newbie figure out a workout split :) I love lifting weights too and have mainly joined Pilates to help with posture and back pain! So I would like to continue strength training

Pilates reformer burned like a B, I can lateral raise heavier weights just fine but moving on the reformer with my arms was PAINFULLLL. Whyyy is this
