Picked up 30 Day Shred for the first time in 5 years whilst on furlough and am almost finished.
What next? I could carry on alternating levels 2 and 3 but what else can I try, especially want to tone up arms and thighs (my abs are OK)?
Btw I'm 55 with an iffy knee so nothing too 'jumpy' (I do the Anita version of jumpy stuff on 30DS).
