I wish I had a tire!!
Since I don't, I'll be doing the intermediate challenge myself, except for myself I'm requiring 7 days, with 60min/day.
Running (45min), Swim (30min), Cycling (30min), Zumba (60min) = 165min
Zumba (60min), Run (30 min) = 90min
Run (15 min), Swim (30 min), Zumba (60 min) = 105min
We'll do the lift challenge, 3 days strength training means I can try 3 new lifts.
40 min circuits ~leg lift machine
40 min circuits ~back extensions with medicine ball
