Well, Ive sort of worked into a routine at my gym. After going there a little over a year now, Ive figured out when everyone is going to do what. I will post my routine, and if you like it, use it, and if you don't, then oh well.
All rounds are 3 minutes and I'm not going to include what I do to stretch.
1. 3 rounds of shadow boxing and ring work mixed in with each other.
2. Hit the heavybag for 4 rounds, and at the final 30 seconds of each round, just punch it as fast and hard as I can.
3. Do 80 sit ups in a row with a 5lb weight on my chest and on an incline board on a 45 degree angle.
4. Hit the mits for 3-4 rounds.
5. Bob and weave under the rope for 2 rounds.
6. Jump rope for 3 rounds.
7. Hit the speed bag if its open or up.
8. Hit the double end bag if its up
9. Walk on the tread mill for 15 min.
