I trained outside today since my session had overhead pressing. It was 39 degrees and kind of nice.
I liked the full body template with power cleans. Are you without a squat stand forever or is this a short term inconvenience? If it’s long term then I think you could built some boxes or squat stands fairly cheap. If you do boxes then you could make them so that they work for cleans from blocks. Another benefit would be setting the bar high for overhead work.
If you want to go the squat stand route then you could check out @flappinit’s creation here.
You could also settle for front squats and clean the weight into position.
